Self-discovery and self-development are essential aspects of personal growth and understanding oneself. They involve exploring your values, strengths, weaknesses, beliefs, desires, and aspirations, and working towards becoming the best version of yourself. Here's a breakdown of both concepts:
1. Self-Discovery:
Self-discovery is the process of gaining insight into your true identity and understanding who you are at your core. It involves introspection, reflection, and exploration of various aspects of your life. Here are some key elements of self-discovery:
a. Reflection: Take time to reflect on your thoughts, emotions, and experiences. Consider what makes you happy, what motivates you, and what brings you fulfillment. Reflect on your past experiences and the lessons you have learned from them.
b. Values and Beliefs: Identify your core values and beliefs. These are the principles that guide your behavior and decisions. Understanding your values helps you align your life with what matters most to you.
c. Strengths and Weaknesses: Recognize your strengths and weaknesses. Discover your natural talents, skills, and abilities, and leverage them to achieve your goals. Acknowledge your weaknesses and areas for improvement to focus on personal growth.
d. Passions and Interests: Explore your passions and interests. Identify activities or subjects that ignite your enthusiasm and make you feel energized. Engaging in activities you love can enhance your self-discovery process.
e. Life Purpose: Reflect on your life purpose and what gives your life meaning. Discovering your purpose involves understanding how you can make a positive impact on the world and find fulfillment in your endeavors.
2. Self-Development:
Self-development refers to the intentional actions and efforts you undertake to improve yourself and reach your full potential. It involves continuous learning, skill-building, and personal growth. Here are some ways to foster self-development:
a. Learning and Education: Engage in lifelong learning. Read books, take courses, attend workshops, and acquire new knowledge and skills that align with your interests and goals. Expand your horizons and stay curious.
b. Goal Setting: Set specific, measurable, achievable, relevant, and time-bound (SMART) goals. Break them down into smaller milestones and work systematically towards their achievement. Regularly review and adjust your goals as needed.
c. Personal Growth Practices: Cultivate habits that contribute to personal growth, such as mindfulness meditation, journaling, regular exercise, and healthy self-care routines. These practices can enhance self-awareness and well-being.
d. Seeking Feedback: Be open to receiving feedback from trusted individuals. Feedback provides valuable insights into areas where you can improve and grow. Actively seek constructive criticism and use it as an opportunity for self-development.
e. Embracing Challenges: Step outside your comfort zone and embrace challenges. Taking on new experiences and overcoming obstacles fosters personal growth and builds resilience. Embrace failure as a learning opportunity and persevere.
Remember, self-discovery and self-development are ongoing processes. They require self-reflection, commitment, and a willingness to adapt and evolve. By embarking on this journey, you can gain a deeper understanding of yourself, unlock your potential, and lead a more fulfilling life.

Biography:
Professor Saul Cunningham's first experience of research was as an Honours student at Monash University. He then received a Fulbright Award to support Ph.D. studies in the USA with field work in Costa Rica.
Having been awarded his Ph.D. in 1995, he returned home to Australia and commenced post-doctoral projects at Macquarie University, before joining CSIRO in Canberra as a Research Scientist. Over a 17 year period with CSIRO, Professor Cunningham developed a research program focusing on the challenge of maintaining biodiversity in landscapes dedicated to agricultural production.
He has worked with farming industry groups, local landholder groups, and a wide network of international colleagues with shared interests.
In 2015 the Ecological Society of Australia honoured Professor Cunningham with the ""Australian Ecology Research Award"". He was a contributor to the Intergovernmental Platform for Biodiversity and Ecosystem Services (IPBES) Assessment Report on Pollination and Food Production, published in 2016.
Professor Cunningham has been Director of the Fenner School of Environment & Society since 2017.

Kathleen (Kate) Harriden (PhD candidate) from the Australian National University (anu.edu.au). Tells the story of how she came to work on water management, incorporating indigenous science into her projects.
This clip has been created by the Research School of Earth Sciences (rses.anu.edu.au). These resources are part of a comprehensive program, curriculum matched to the unit 'Unit 3 Living on Earth - extracting, using and managing Earth resources'.
Kate's bio:
B. As (Thai) (ANU), B. Sc (ANU), GradDip. PA (Canberra), M. A. (As) (ANU), M. Geog (ANU), PhD candidate (ANU)
Kate is an advocate of multidisciplinary and transdisciplinary research, as evidenced in much of her previous research from slums as environmental actors to opening the black box of intra-household water use. She is particularly interested in including traditional ecological knowledge in contemporary urban water management practices and policy development. She will continue combining water science with social science during her PhD research.
Kate is the current holder of the Icon Water Aspi Baria Scholarship. She has held positions on a number of committees, including the Aust. Water Assoc. (AWA) ACT Branch Committee and the Aust. Assoc. for Environmental Education (AAEE) ACT and National committees.
Her Master of Geographical Sciences sub-thesis, “Fluid boundaries: the hyporheic zone of a tropical, tidal river”, investigated the hyporheic zone of a small site on the Bang Pakong River, Thailand. Whereas her Master of Arts (Asian Studies) sub-thesis, “Stormwater: why waste it”, examined the influence of different ecological knowledge systems on the way stormwater is perceived and valued.
Kate has worked both as an independent researcher and held a number of positions across all levels of government. This PhD project was inspired by her most recent public sector position, in the ACT Government's Healthy Waterways project. The Healthy Waterways project will see the construction of a series of water sensitive infrastructure projects, across a number of catchments, to contribute to improved water quality in the Murrumbidgee Catchment.
While working as an independent researcher, Kate developed a water diary, variations of which are now widely used in many research projects examining intra-household water flows. This research lead her to a guest lecturer role in a post-graduate ANU unit, Exploring Gender and Development, from 2008 - 2012. She was also the co-ordinator of the organizing committee for the international conference on water’s social dimensions "Tapping the Turn", held at ANU in 2012 (https://www.youtube.com/watch?v=QM0sk2Z6wSc). Kate was a guest editor of the Tapping the Turn special edition of the Australasian Journal of Environmental Management (V. 20 No. 3 2013). From 2009 - 2014 she was the co-ordinator of the international network of household water use researchers. She has also translated children’s books (from English to Thai) and fables and folk tales (from Thai to English), that are in the process of being published.

In this video That Bio Doc tells you what evolution is NOT all about. TBD discusses some of the most common misconceptions and misunderstandings about evolutionary theory. And if you have an ax to grind against evolution, it shouldn't be because of any of these reasons!
In this video, That Bio Doc talks about the key tenets of modern evolutionary theory and the large body of evidence upon which the theory is built. Learn how natural selection is able to gradually shape species over time and how evidence, such as the fossil record, anatomy, molecular biology, and biogeography provide strong evidence in support of evolutionary theory.
Charles Darwin didn't invent the concept of evolution. In fact, evolutionary thought had been around since ancient Greece, and perhaps even before that. In fact, Charles Darwin's own grandfather had expressed ideas about evolution decades before Charles published On the Origin of Species. What Darwin did do, however, is provide a comprehensive body of evidence in support of evolutionary theory and propose the true mechanism by evolutionary change occurs - natural selection. In this video, That Bio Doc introduces you to early evolutionary ideas and describes how Darwin's journey on the HMS Beagle, as well as the writings of other brilliant contemporaries, led to the development of modern evolutionary theory.
Today, it is difficult to think about evolution without also thinking about genetics. However, that wasn't always the case. Although Gregor Mendel performed his pioneering experiments following the inheritance pattern of several traits in pea plants just a few short years after the publication of On the Origin of Species, it took decades before the fields of Darwinian evolution and Mendelian genetics were fused together in the modern synthesis. In this video, That Bio Doc discusses Mendel's experiments and how the results of those experiments laid the foundation for our modern understanding of genetics and evolutionary biology. Learn about key genetic concepts such as dominance, the difference between genotype and phenotype, and how to calculate the odds of inheriting specific traits based on the genetic make-up of the parental generation using mathematical operations and Punnett squares.
Speciation occurs when a population of a species becomes so different from other members of its species that it can no longer be considered part of the same species. This occurs through a process known as macroevolution. In this video, That Bio Doc discusses the different ways in which species can diverge from each other, why barriers, both physical and genetic, are so important for speciation events, and what happens when to closely related species reconnect.
Homologous and analogous structures provide a wealth of information about the evolution of species. In this video, That Bio Doc talks about the differences between the two types of structures and how they inform us about the evolution of species and their interrelatedness.
Natural selection is the mechanism by which most evolutionary change and all adaptation occurs. That Bio Doc introduces you to the topic of natural selection by first discussing artificial selection, then teaching you why heavily used traits tend to improve over time, while disused traits tend to degrade as a result of selection pressures.
Sexual selection is a form of natural selection that results in the accumulation of sexually dimorphic traits, which are structures or behaviors found in one sex of a species but not the other. At first glance, the high survival cost of traits such as bright plumage or large antlers may seem anti-evolutionary, but as That Bio Doc explains, survival is only half of the equation when it comes to reproductive fitness. Come see why sexual selection, which was once a source of consternation for evolutionary biologists, may provide the best evidence for how natural selection shapes species over time.
Have you every wondered how we know the age of Earth or how long it has been since the dinosaurs ruled the planet? It turns out that the answer is within the rocks themselves. In this video, TBD discusses the concepts of modern geology and how rocks can actually be used as clocks! TBD describes the different types of rock, which ones contain the fossil archaeologists and biologist are interested in, and which ones tell us how old those fossils (and the planet!) really are.
In this video, That Bio Doc discusses how radioactive isotopes such as carbon-14, uranium-238, uranium-235, and potassium-40 can be used to determine the age of a rock sample. Absolute dating techniques using these radioactive isotopes are the primary way in which the age of rock strata, including the fossils contained within them, are determined.
The fossil record is one of the best sources of evidence to support evolutionary theory. In this video, That Bio Doc describes how fossils are made, what they tell us about life, and how the fossil record supports the theory of evolution.
Islands are a treasure trove of information about the process of evolution. The extreme genetic isolation, open ecological niches, and unique habitats found on islands leads to many interesting evolutionary changes in the species that inhabit them. In this video, TBD talks about the two major types of islands found on the planet and how island life shapes species and what that tells us about evolution.
That Bio Doc talks about biogeography and what it teaches us about evolution and the geologic history of Earth. Learn how the locations of species and of fossil remains provides information about the history of species and of Earth itself. TBD also discusses the terrestrial biomes found around the globe and the impact those environments have on the species that live in them.
Pangea was the Earth's last, but not only supercontinent. In this video That Bio Doc explores the formation and eventual destruction of Pangea by geologic forces, and the effects that Pangea had on life both during and after its existence.
The evolution of complex traits such as certain behaviors, structures, and molecular pathways occurs through normal evolutionary pathways. However, these traits have sometimes been pointed to by opponents of evolutionary theory as being irreducibly complex, and thus, not able to have been produced through evolutionary mechanisms. In this video, That Bio Doc will talk about what the argument from irreducible complexity does really work and explain how mutations, such as gene duplications, can readily explain the evolution of these traits.
Development is one of the seven properties that all living things possess. It is both an essential and complex process, as well as one that does not tolerate mutations very well. However, changes to the developmental process are often required for the evolution of species. In this video That Bio Doc will discuss how evolutionary changes to development occur and how those changes serve as evidence for the evolutionary origins of species.
Phylogenetics is a branch of biology that classifies organisms according to the evolutionary relationships. In this video That Bio Doc discusses phylogenetics and cladistics and how biologists use similarities and differences between species to determine their evolutionary histories.
This is the first in a series of videos where That Bio Doc takes on a tour of the evolutionary history of life on Earth. In this video, TBD talks about the Precambrian supereon, which covers the first ~4 billion years of life on the planet Earth. Watch and learn what early life on Earth looked like, how oxygen was introduced into the Earth's atmosphere, and how endosymbiosis changed life on Earth forever!
In this video, That Bio Doc introduces you to life in the Cambrian Period (541 - 488.3 mya). This is the second video in a series of videos about the evolutionary history of life on Earth. During the Cambrian Period, we see the first appearance of many modern animal phyla in the fossil record. This phenomenon, known as the Cambrian Explosion, is one of the most interesting events in the fossil record. In this video, TBD introduces you to many of these animal phyla and describes the unique characteristics that define each phylum.
During the Silurian period, life would recover from the end-Ordovician mass extinction. The gradual warming of the Earth and the re-filling of the shallow seas would lead to a radiation of marine life. Meanwhile, plants would further establish themselves on land. During the first half of the period plants would diversify into distinct groups of seedless nonvascular plants and by the end of the period, the first vascular plants appear in the fossil record. Finally, during the Silurian, animals would appear on land for the first time in the form of terrestrial arthropods. In this video, That Bio Doc talks about what life was like during the Silurian Period, 443.8 - 419.2 million years ago.
During the early Permian, life on land and in the ocean would look much as it did at the end of the Carboniferous. However, the changing climate, from warm and moist during much of the Carboniferous, to cool and arid at the start of the Permian, would lead to many changes throughout the period. By the end of the Permian, many of the water-loving plant species would be replaced by seed ferns and conifers, plants that were better adapted to the drier environment of Pangea. The amphibians, which had dominated aquatic and terrestrial biomes during the Carboniferous, were replaced by rapidly diversifying reptiles. However, the Permian period would end with the single greatest catastrophe life on Earth has ever seen. The end-Permian mass extinction, known as the Great Dying, would cause the extinction of nearly 97% of species on the planet.
During the Ordovician, the animal phyla that first appeared in the fossil record during the Cambrian period would diversify giving rise to several highly diverse groups of animals. This would result in increased competition in the ocean where all living things still resided. Well, almost all living things because during the Ordovician, plants would make their first appearance on land. In this video, That Bio Doc talks about what life was like during the Ordovician Period, 488.3 - 443.8 million years ago.
The Devonian, the Age of Fish, saw a massive diversification of fish species. In particular, the bony fish, which first appeared during the Silurian, diverged into two major groups - the ray-finned fish and the lobe-finned fish. Perhaps due in part to the increased competition in the Devonian ocean, a lineage of lobe-finned fish would give rise to the first terrestrial vertebrates, the tetrapods, during the latter half of the period. Also on land, plants got their first true roots. The Devonian would end in a mass extinction event that would wipe out nearly 75% of the extant species on the planet.
During the Carboniferous life would recover from the mass extinction event at the end of the Devonian. Due to the warm, moist climate terrestrial plants would evolve greatly during this period, with the vascular seed plants beginning to dominate terrestrial forests, instead of their seedless predecessors. The bountiful forests would generate so much oxygen that the atmospheric oxygen concentration would reach its highest point in Earth's history. This in turn would give rise to some of the largest terrestrial arthropod species to ever exist. Terrestrial vertebrates continued to diversify giving rise to the first true amphibians and by the end of the period, the first true reptiles. In this video, That Bio Doc describes what life was like during the Carboniferous 358.9 - 298.9 million years ago.
The Triassic Period is the first of the Mesozoic Era. Following the Great Dying at the end of the Permian, the vast majority of multi-celluar life on the planet had gone extinct. During the Triassic, those species that remained would radiate and repopulate the Earth. Life in the Triassic would differ greatly from the periods before it because the Triassic would mark the beginning of almost 200 million years of reptilian dominance of the air, land, and sea. It would also mark the beginning of the seed plants' dominance of Earth forests.
The Jurassic Period would mark the beginning of the dinosaurs' dominance of terrestrial Earth, but also the end of Pangea. Reptiles continued their dominance of the air, land, and sea during the Jurassic, but also have to deal with a world that was literally shifting beneath their feet. The Jurassic would also see the appearance of the first true birds and mammals, and for once, wouldn't end with a mass extinction.
The K-Pg mass extinction event marked the end of the Cretaceous Period, but also the end of the Mesozoic Era. During the Cenozoic, life would recover and the Earth would be replenished by the species that survived. Like we saw following the Great Dying at the end of the Permian, life would be forever changed after the K-Pg mass extinction event and the ecological niches once dominated by reptiles would be taken over by birds, mammals, and fish.
The Cretaceous Period marked the peak of dinosaurian dominance, but ended with their extinction. In fact, the Cretaceous would mark the peak of reptilian dominance, but would also be the last period in which reptiles would dominate the Earth. The end of the Cretaceous would be marked by the fifth and final mass extinction in the history of life on Earth.

After the Emancipation Proclamation, blacks fill local and national offices, but white southerners are determined to pass new state laws to curtail this progress.
Professor Eric Foner of Columbia University discusses the Black Codes, which were written by white southerners to force blacks to keep working on plantations.
American History: From Emancipation to the Present (AFAM 162)
Between 1865 and 1877, several plans were developed by which the Confederate states could be readmitted to the Union and the residents of the states given full citizenship rights. It was far from clear, however, which plan would do a better job maintaining the social peace and protecting African Americans' ability to earn a wage, raise a family, own land, and exercise the right to vote. In this lecture, Professor Holloway outlines the contours of the Ten Percent Plan, Presidential Reconstruction, and Radical Reconstruction, and he explains how these plans embraced a variety of approaches to reuniting the disparate states. As Professor Holloway explains, Reconstruction greatly enhanced the rights of African Americans, while also circumscribing their lives by new political, economic, and social initiatives.

The United States of America was born out of the yearning of the many people who had traveled there from the old world of Europe to be free of the imperial powers that had dominated them for centuries. To have democracy, liberty, justice for all and to take command of their own destiny.
The birth of the American nation was a painful one, first by having to fight against the forces of the British and then against the indigenous people of North America, within and from outside of the new borders they had declared. In between the many conflicts, the new nation had to establish its own laws, political system and even its own culture none of which developed overnight.
Obviously, there would not always be a consensus. Over the century after 1776 when the United States of America was born, while growing under a political union of the states that it was composed of, it also saw the widening of a cultural divide between the industrious northern states and the agricultural southern states. Perhaps more than anything else, the two sides of this divide found themselves at odds over the question of slavery.
The ethics of owning a person as property became a legal battle between those in support of the practice and those opposed in American courts and halls of power. Eventually, the dispute of course became a real battlefield. More Americans died in the American Civil War that raged on the North American continent between 1861 and 1865 than in any other war in which Americans have fought throughout its history.
And while the battles have long ended, the ramifications of the civil war continue to be felt to this very day in America over issues such as culture and of course race. So, let us delve into the history of this dark chapter of American history.

A redox titration is a titration in which the analyte and titrant react through an oxidation–reduction reaction. As in acid–base titrations, the endpoint of a redox titration is often detected using an indicator. Potassium permanganate (KMnO₄) is a popular titrant because it serves as its own indicator in acidic solution.

Let's explore how the graph of stopping potential vs frequency can be used to calculate the Planck's constant experimentally!
From Einstein's photoelectric equation, this graph is a straight line with the slope being a universal constant. This slope has the value of h/e. In an effort to disprove Einstein, Robert Millikan conducted experiments with various metals only to conclusively prove him right. Millikan, Einstein, and Max Planck, all won a Nobel prize for their contribution to photoelectric effect and giving birth to the quantum nature of light!

Let's explore how the quantum theory of light explains the below experimental results of photoelectric effects.
1. The kinetic energy of the photoelectrons are independent of intensity but depend on frequency.
2. Below a minimum frequency called the threshold frequency, no photoelectric effect takes place, even if the light has very high intensity.
3. Photoelectric effect is almost instantaneous.

Dr Mahdiyeh Razeghi from the Australian National University (anu.edu.au) describes how satellites are used to accurately determine how much water there is, and where it is in the environment. This as part of a series of educational videos on our Earth's water.
This clip has been created by the Research School of Earth Sciences (rses.anu.edu.au). These resources are part of a comprehensive program, curriculum matched to the unit 'Introduction to Earth systems'.
This video touches on the following curriculum descriptors:
- The modern atmosphere has a layered structure characterised by changes in temperature: the troposphere, mesosphere, stratosphere and thermosphere (ACSES022)
- Water’s unique properties, including its boiling point, density in solid and liquid phase, surface tension and its ability to act a solvent, and its abundance at the surface of Earth make it an important component of Earth system processes (for example, precipitation, ice sheet formation, evapotranspiration, solution of salts) (ACSES024)

In this video I will go over three of the word problems from your textbook' numbers 8, 9 and 11. If you don't have a Nelson textbook that's okay as I have written out the questions for you. Make sure that you try the questions first!
We will look at various logarithmic scales including Richter scale calculations for comparing the intensities of earthquakes, decibels and sound, pH and calculating hydronium ion concentrations.
Lots of practice with various types of equations. Watch out for inadmissible solutions Most questions involve quadratics so you must be good at switching between logarithmic and exponential forms. Be a log bae!!
Solving exponential equations by taking the log of both sides, factoring, finding a common factor and also rewriting using the same base. Lots of practice questions from your textbook to give you a good selection of examples.
Techniques such as finding a common base, taking the log of both sides and applying logarithmic rules to isolate x, and factoring. Remember that the log of a number can be evaluated on your calculator!
Product law, quotient law and power law for logarithms. Proof of these laws is in your text book and you should take a look at them. Lots of textbook examples for you to follow along with!
Be a Log Bae! That's all you need to remember to help you switch between the exponential form and the logarithmic form. Lots of practice with different homework questions.
How to graph a transformed Logarithmic function using the points of its reciprocal function *i.e the exponential function. Using mapping rules and stating domain and range as well as the transformations
Graphing the exponential and finding the logarithmic function from its points. Basic logarithmic calculations. Note that at 3:39 I mistakingly identify the y axis as y=0 when it should be labeled x=0

Ferromagnets with high retentivity and coercivity are used as permanent magnets (hard magnets), while the ones with low retentivity & coercivity (soft magnets) are used as cores in electromagnets. But all ferromagnets have high permeability.
Let's explore these differences between the permanent magnets and the ones used in electromagnets, by looking at their hysteresis loops.

Magnetic susceptibility is a measure of how readily materials tend to get magnetized. Diamagnets have a small negative susceptibility while paramagnets have a small positive susceptibility. Ferromagnets have a large susceptibility.
Relative permeability is a measure of how readily materials allow the field lines to pass through them, compared to vacuum.

http://www.rootmath.org | Calculus
In this video we use a u-sub and the natural log rule to integrate tanx.
http://www.rootmath.org | Calculus
In this video we use a little 'trick' to help us integrate secx. Ultimately we will rely on a u-substitution and the natural log rule to evaluate the integral.
http://www.rootmath.org | Calculus
In this video we go over a classic example of using u-sub and the natural log rule to evaluate an integral. Specifically we look at the function 1/xlnx.
http://www.rootmath.org | Calculus
Our third example of using u-substitution with the natural log rule to solve evaluate and integral. In this example we are evaluating a function involving tan and sec
http://www.rootmath.org | Calculus
Here we find an anti-derivative (indefinite integral) for a function involving a fraction and e to a power. To do this we use u-substitution and the natural log rule for integrals.
http://www.rootmath.org | Calculus
We explore coming u-substitution with the natural log (ln) rule for integration. This will allow us to find the integral of an even wider range of functions.
http:www.rootmath.org | Calculus
In this video we evaluate a definite integral with a u-substitution. When we use u-substitution we must change the limits of integration.
There is another technique that does not involve changing the limits of integration and we'll explore that idea in this video also.
http://www.rootmath.org | Calculus
In this example we use u-substitution to find an integral involving sin and cos.
http://www.rootmath.org | Calculus
In this example we find the 2 integrals that involve a square root. Each integral will require a u-sub.
http://www.rootmath.org | Calculus
This is our third example of using u-substitution to solve an integral. In this example we learn how to adjust for a constant
http://www.rootmath.org | Calculus
This video is an introduction to the idea behind u-substitution. This is a very important technique for solving integrals!
http://www.rootmath.org | Calculus
This video is an introduction to the idea behind u-substitution. This is a very important technique for solving integrals!
http://www.rootmath.org | Calculus
We learn how to re-write and simplify integrals to make them easier to solve. This is the third example.
http://www.rootmath.org | Calculus
We learn how to re-write and simplify integrals to make them easier to solve. This is the second example.
http://www.rootmath.org | Calculus
We learn how to re-write and simplify integrals to make them easier to solve. This will allow us to integrate more complicated expressions than we could in the past.

The definite integral and the fundamental theorem of let us compute the average value of a function over an interval.
http://www.rootmath.org | Calculus
Area trapped under the x-axis is interpreted as 'negative' area by the definite integral.
http://www.rootmath.org | Calculus
Some basic but useful properties of integrals.
http://www.rootmath.org | Calculus
In this video we will do a few more examples of using the fundamental theorem to evaluate definite integrals. This should help you get a better understanding of how the theorem works and how to use it.
http://www.rootmath.org | Calculus
This video is an introduction to the first fundamental theorem of calculus. It will mostly focus on evaluating definite integrals and how that relates to area under a curve.
http://www.rootmath.org | Calculus 1
This video defines a Riemann Sum and a Definite Integral. This is built upon the previous videos and just slightly refines what we've already seen so far.
To see an example of a Riemann Sum where delta x_i is not equal to (b-a)/n see: http://www.youtube.com/watch?v=W2309ZF5MYg
http://www.rootmath.org | Calculus 1
This is a slightly more advanced example. It illustrates the point that the width of the rectangles does not need to be constant.
http://www.rootmath.org | Calculus 1
This video builds upon our previous knowledge of finding exact area, but here we introduce the idea of a left hand sum, or lower sum.
http://www.rootmath.org | Calculus 1
Another example of finding exact area under a curve by taking the limit of a sum.
http://www.rootmath.org | Calculus 1
The exact area under a curve is the sum of an infinite amount of infinitely small rectangles. We'll derive this amazing result by taking the limit of a sum.
http://www.rootmath.org | Calculus 1
Using 4 rectangles to estimate the area under a curve. We'll combine what we've talked about so far, and emphasis the importance of finding the height of the "ith" rectangle.
This is video 4 in series on summations. In this video we combine the 3 formulas and 2 properties of sums we learned in the last videos to solve more complex sums.

The area under a curve is difficult to find so we will estimate the area by using rectangles.
http://www.rootmath.org | Calculus
Before we learn more advanced integration techniques these common antiderivative, and antiderivative rules will allow us to find some basic antiderivatives.
http://www.rootmath.org | Calculus
Some basic properties of antiderivatives. We see the antiderivative of a constant and the antiderivative of a sum.

http://www.rootmath.org | Algebra
This will be a review of how fractions cancel. Understanding these basic rules now will make everything easier later on in the course when things get more complicated.
http://www.rootmath.org | Algebra
Multiplying fractions is the easiest thing to do with fractions! This will be a quick review of how fractions multiply. We'll use this throughout the algebra course.
http://www.rootmath.org | Algebra
Subtraction is a very poorly behaved operation. It isn't commutative and it isn't associative. But we can force it to be have by turning subtraction into addition!
a - b = a + (-b)
http://www.rootmath.org | Algebra
The associative property tells us that is doesn't matter how we group addition or multiplication. The property can be written like this:
a + (b + c) = (a + b) + c
a(bc) = (ab)c
http://www.rootmath.org | Algebra
In this video we learn the commutative property of addition and multiplication. The commutative property tells us that it doesn't matter which order we add or multiply in. We can right this rule like this:
a + b = b + a
ab = ba
Although this rule is very simple its very important!
http://www.rootmath.org | Algebra
In this video we'll review important sets of numbers:
Natural Numbers
Integers
Rational Numbers
Real Numbers
Complex Numbers
http://www.rootmath.org | Algebra
Welcome to the Algebra course. We'll get started by introducing variables and seeing examples of them in simple equations.
http://www.rootmath.org | Linear Algebra
We prove that the diagonals of a parallelogram are perpendicular if and only if the sides of the parallelogram are the same length.
http://www.rootmath.og | Linear Algebra
The definition of orthogonal: Two vectors are orthogonal when their dot product is zero.
http://www.rootmath.org | Linear Algebra
A brief example of using the dot product definition of the angle between two vectors to find that angle.
http://www.rootmath.org | Linear Algebra
The dot product helps us define the angle between two vectors. In this video we use the law of cosines and the dot product to help us define the angle between two vectors.
http://www.rootmath.org | Linear Algebra
We learn the definition of the dot product and we see an example. In the next video we will see how this definition helps us to define the angle between two vectors.
http://www.rootmath.org | Linear Algebra
We learn some basic properties of vectors like commutativity and associativity of addition, along with others.
http://www.rootmath.org | Linear Algebra
This is a proof that vector addition is commutative and associative. The proof relies on the same properties for the real numbers.
http://www.rootmath.org | Linear Algebra
We derived the length of vectors with 2 and 3 components using the Pythagorean Theorem. Now will will extend the notion of vector length to higher dimensions.
http://www.rootmath.org | Linear Algebra
In this video we'll define R^n. This will hopefully put us on the same page for notation that is coming up in the course.
http://www.rootmath.org | Linear Algebra
In this video we'll derive a formula for finding the length of a 3-dimensional vector. We'll also briefly discuss how to find the length of a vector with more than 3 components.
http://www.rootmath.org | Linear Algebra
We'll look at how to graph vectors with 3 components using 3-dimensional axes.
http://www.rootmath.org | Linear Algebra
u - v = u + (-v)
Since we know how to add vectors and multiply by negative one, we can also subtract vectors. Vector subtraction has geometric significance that we will utilize in a later video.
http://www.rootmath.org | Linear Algebra
When you multiply a vector by a scalar you simply multiply each component by that scalar. Since we can multiply a vector by -1 we can have -v. With this we have the tools we need to talk about vector subtraction (next video)
http://www.rootmath.org | Linear Algebra
Vectors are added by adding corresponding components. Graphically we add vectors with a "head to tail" approach.
http://www.rootmath.org | Linear Algebra
To find the length of a vector we simply use the Pythagorean Theorem. The components of a vector form the base and height of a right triangle. The length of the vector is simply they hypotenuse of that triangle.

http://www.rootmath.org/calculus/limits-that-fail-to-exist
Our third example of a limit that does not exist. This limit does not exist because the function oscillates as x approaches 0 and so the limit does not exist.
![1.3 Limit that Fails to Exist [02] - 1/x^2](https://i.ytimg.com/vi/DGnR49P-xf0/maxresdefault.jpg)
http://www.rootmath.org
http://www.rootmath.org/calculus/limits-that-fail-to-exist
A limit does not exist when it 'grows without bound.' Intuitively, if a function keeps getting bigger as you approach the limit value then the limit does not exist.
![1.3 Limits that Fail to Exist [01] - |x|/x](https://i.ytimg.com/vi/fU7JNYBxiaY/maxresdefault.jpg)
http://www.rootmath.org
http://www.rootmath.org/calculus/limits-that-fail-to-exist
Some limits don't exist. The absolute value of x over x, |x|/x, has no limit as x approaches 0. This is because there is a jump in the graph at zero, or a jump discontinuity. This causes the value of the function to differ at the two sides of the jump and so the limit fails to exist.

This lesson walks through 12 climate types of the world. Organized into 9 climates classified by latitude and 3 climate types that can be found at any latitude, Mr. Rueschhoff explains each climate, where they are found, the climate factors that contribute to their creation, and their associated biome.
Climates discussed are Tropical Wet; Tropical Wet/Dry; Humid Subtropical; Humid Continental; Mediterranean; Marine West Coast; Sub-Arctic; Tundra; Icecap; Arid, Semi-Arid; and the Highland Climates.
Together with the previous lesson on the Five Factors of Climates and Biomes, viewers should be able to up their finger on the globe and have a good idea of what it is like there in terms of climate.
While accessible to anyone, this lesson is specifically written to address the educational standards of the Texas Education Knowledge Standards for the World Geography studies course.
The lesson builds upon our look at latitude's impact on seasons and adds four more factors to explain how the Earth's climate is created. In addition to Latitude--the most important factor--are Elevation, Wind Currents, Ocean Currents, and Topography.
The lesson reviews how latitude greatly influences temperature on Earth and introduces how Elevation also has an impact on temperature of regions on Earth. Next, the lesson introduces Wind and Ocean Currents. It explains how convection drives our winds and creates the Hadley Cell and Inter-tropical Convergence Zone (ITCZ) that has a profound impact of climate in the tropics and creates the conditions for some the world's largest deserts.
Influenced by these Wind Currents are the Ocean Currents which are in a constant cycle of warm and cold water exchange between the equator and poles. Why the waters off of the west coast of a continent are usually cool while waters off the east coast are warm are explained. (Hint, it has to do with the Coriolis Effect). The role that El Nino and the North Atlantic Drift have in shaping the climate of the Americas and Europe are discussed as is the impact of Continentality.
The lesson concludes by discussing Topography's role in our climate--chiefly due to the Rainshadow Effect.
While useful to all audiences, this lesson is specifically designed to address elements of the Texas Education Knowledge Standards for the World Geography Studies Course.
This video lesson explains why we have seasons on Earth. Specifically, it examines the Earth-Sun relationship. Viewers will learn it isn't just that the Earth rotates every 24 hours or even that it revolves around the Sun ever 365.25 days. Rather, what is special is that the Earth is titled that means that the Sun's energy (solar insolation) is distributed unevenly on the Earth's surface.
The big takeaway--beyond the fact that the Earth's seasons are caused by the Earth's revolution and tilt--is that latitude is an extremely important factor in determining what makes up the characteristics of a location.
Mr. Rueschhoff uses models to show the stages of this Earth-Sun relationship throughout the year to explain what Solstices and Equinoxes are. He concludes by breaking latitude into three bands (High, Middle, and Low) and explain how these three latitude bands have uniquely different seasons--it's not just Spring, Summer, Fall, and Winter!
A lesson that can be viewed and appreciated by all, but is specifically designed to address standards in the Texas Education Knowledge Standards (TEKS) for the World Geography studies course.
This video lesson looks at external factors that shape the Earth's landforms: weathering, erosion, and deposition. This examination of physical geography and geology aspects of the world includes looking at the differences between chemical and physical (or mechanical) weathering, how rain, wind, ice (glaciers), and even gravity moves sediment, and then how deposition of sediment creates landforms such as river deltas as well as produces fertile areas such as the North European Plain through the deposition of loess.
In addition, a review of what soil is and how it is created is included as well as how these processes create sedimentary rock.
This lesson is designed to not only inform all audiences, but also to focus on the Texas Education Knowledge Standards for the World Geography studies course.
CORRECTION: AT 8:58, I stated that if there is just one Continental Plate you would have Convergent Subduction. I meant to say OCEANIC Plate. Sorry.
Ever heard someone say you're "making a mountain out of a molehill?" Well, I don't actually know what a molehill is (actually, I think I do), but in this lesson, we will examine the Earth's forces that creates its mountains--namely Continental Drift and Plate Tectonics.
This lesson begins by looking at the composition of the Earth and discover that its core, mantle, and crust make it much more like a baseball, than a blue marble that some have called it.
We then look at the outside of the Earth and find that it also has stitches, just like a baseball. Here we learn of Alfred Wegner's examination of the Earth which used records of fossils and rock formations to assert that the continents move--giving rise to the theory of Continental Drift.
While the geology community thought that Wegner was crazy, Harry Hess joined the Navy and through the use of sonar mapped the ocean floor and with carbon dating of the ocean crust, discovered Wegner was right and explained how the continents move through a process not unlike a lava lamp (interested, gotta watch the video--hint, it's through convection of the magma in the asthenosphere).
The lesson then looks at the three major ways that tectonic plates will move in relation to each other: divergence, convergence, and transform boundaries and discover that these moving plates create landforms such as mountains and volcanoes--and even rift valleys.
Because of the different densities, the lesson points out that if there is an oceanic crust involved in a collision of tectonic plates, it will cause something called Convergent Subduction which creates the subduction zone of the Ring of Fire.
