Windows Forms is a classic software framework for the development of Desktop graphical user interface (GUI) apps for Microsoft Windows. It is based on the .NET platform and the C# language and provides a programming model and rich UI control library for building GUI apps. Additionally, the Visual Studio IDE is a powerful visual UI builder for Windows Forms, where developers design the user interface by dragging and dropping UI controls and configuring their properties and events.

In a nutshell, the Internet of Things is the concept of connecting any device (so long as it has an on/off switch) to the Internet and to other connected devices. The IoT is a giant network of connected things and people – all of which collect and share data about the way they are used and about the environment around them.
In this dev lesson let’s look into the basic principles of IoT and IoT microcontrollers. I also have an example prepared in TinkerCad so you can see the concepts in practice.

Source control management (SCM) systems are widely used among software developers. SCM systems help you collaborate on code with your team, isolate your work until it is ready, and quickly troubleshoot issues by identifying who made which changes and keeping a history of every single piece of code that is committed.
In this tutorial, we’ll look at Git and GitHub. Git is an open-source distributed source code management system. It allows you to make a copy of your repository known as a branch. By creating this branch, you can work on your code independently from the stable version of your codebase.
I’ll also show you how to make a portfolio of your projects on GitHub to help you start your first developer job.

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

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 | calculus 1

We take the derivative of the equation of a circle.

http://www.rootmath.org | calculus 1

We learn how to take the derivative of the natural log of x.

http://www.rootmath.org | Calculus 1

We use implicit differentiation to take the derivative of the inverse sine function: arcsin(x).

http://www.rootmath.org | Calculus 1

We use implicit differentiation to take the derivative of arcsec(x).

http://www.rootmath.org | Calculus 1

This will be a basic related rates problem. We'll try to relate the rate at which water is entering to the pool to the rate at which the water level is rising.

http://www.rootmath.org | Calculus 1

This problem is very similar to filling a pool but with an added consideration. This is a very typical related rates problem for a Calculus 1 class. You may find a problem like this on a test or exam.

http://www.rootmath.org | Calculus 1

An introduction to a very interesting problem. I definitely recommend you watch this video before moving on to part 2.

http://www.rootmath.org | Calculus 1

An example that will expand on our understanding of the relationship between extrema and the derivative.

http://www.rootmath.org | Calculus 1

We'll look at the definition of a critical number and how we can find them.

Watching gas bubble up from a pondweed as it photosynthesises can be a great demonstration or student practical. When placed closer to a light , the rate of bubbling will speed up, and as the pondweed is taken further away, the bubbles will slow down again – an instant and visual indicator of the importance of light in photosynthesis.

This video demonstrates how best to use this protocol with your students in the lab, which species of pondweed can be used, how to care for pondweeds and a short explanation on the physiology that allows pondweed to bubble.

A great lab practical for investigating photosynthesis and respiration at GCSE and A-level / post-16. The bubbles produced by pondweed can be counted and the rate of bubbling can serve as an indication of the rate of photosynthesis, or the gas can be collected in a pipette or microsyringe and the amount measured. Students can investigate the effects of either light intensity or the wavelength (colour) of light on photosynthesis.

The ability to accurately observe, dissect and record an organism is a key skill for biology students. Many students are intimidated by the idea of making a scientific drawing, and struggle to develop their skills in this area.

This video will guide you through how to complete a dissection and scientific drawing of a flower. We recommend using Alstroemeria, as they are regularly available in supermarkets. However, there is an alternative version in which students follow in the footsteps of Darwin, making careful observations and dissections of primulas. Primulas are available in garden centres through much of the late autumn, winter and spring months, and flower in the garden in spring.

3:16 Step 7 - slice along the line of symmetry
3:32 Step 8 - continue slicing through the petals
4:00 Step 9 - arrange the parts for drawing
4:21 Step 10 - observe the flower parts
4:55 Step 11 - produce anatomical flower drawing

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

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
http://www.rootmath.org/calculus/trig-limits

Often times a few special trig limits are proven in class. We'll look at one that we'll prove later, and one that we can prove now.

😇😍

😘😙😘

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.

This video lesson builds on the discussion about developing and developed countries in the Population Geography lesson. In this lesson, Mr. Rueschhoff describes the United Nation's Human Development Index, how it is determined, and how it can be used to describe countries of the world.

Each of the HDI's dimensions is discussed: Long, Healthy Living, Knowledge, and Standard of Living. This includes explaining the difference between Gross National Income, Gross National Product, and Gross Domestic Product.

Mean and Expected Schooling is discussed as are literacy rates when discussing the knowledge dimension of the UN's HDI.

The lesson concludes with Mr. Rueschhoff showing the population pyramids of a developed country, developing country, and a newly industrialized country and how these relate to the UN's HDI categories.

Thumbnail photograph was used under a Creative Commons license from NigerTZai (BY-SA 4.0).

This is part 2 of our Agriculture and Economies lesson. In part 1, we went over the agricultural and industrial revolutions that made our economies possible.

In this lesson, we go over the 4 Economic Activities (Primary, Secondary, Tertiary, and Quaternary) and the types of Natural Resources. Then, we go over the types of economic systems. We meet Adam Smith and Karl Marx and discuss Free Market, Command (Socialism & Communism), and Mixed Economies. We also briefly discuss Mercantilism and we describe traditional economies.

While all audiences can benefit from this lesson, it is specifically written for a World Geography studies course satisfying multiple standards within the Texas Education Knowledge Standards (TEKS).

This lesson looks at the way that countries seek to influence each other. In other words, how countries use power.

Calling upon Mr. Rueschhoff's over 23 years of military service his Master's Degree in Military Studies, he describes the Sources of National Power and the Instruments of National Power. These are concepts used by strategic planners in capitals around the globe.

First, the term power is defined and the concept of the Balance of Power is introduced and its role in keeping world peace.

Then, the lesson looks at what makes a nation powerful through the Sources of National Power which are its physical geography, economics, people, national will, and national direction.

But being powerful isn't enough, it is about how you use this power and Mr. Rueschhoff explains that countries use the DIME: Diplomacy, Information, Military, and Economics. These are the Instruments of National Power. Countries will use a blend of these four instruments to avoid war, gain territory, increase trade, resolve conflicts, and form alliances.

The organizations and alliances that are discussed are the United Nations, European Union, NATO, and OPEC.

While useful to all audiences, this lesson is specifically made to address standards of the World Geography studies course in the Texas Education Knowledge Standards (TEKS).

This lesson introduces the viewer to the Four Earth Systems: Atmosphere, Lithosphere, Hydrosphere, and Biosphere.

The lesson explains how each system is made up of sub-components and how each system interacts with the other three systems--all supporting life on Earth.

The Carbon Cycle and Water Cycle are described and the Life Cycle is introduced.

This lesson is designed to satisfy elements of the Texas Education Knowledge Standards for the World Geography studies course.

This lesson walks students through the basic landforms on the Earth. This includes plains, mountains, hills, plateaus, peninsulas, islands, archipelagos, valleys, and canyons. The importance of rivers and the deltas and alluvial plains they create are examined.

The lesson also discusses the difference between oceans, seas, gulfs, and bays. The importance of straits are discussed and how they are the mirror opposite of isthmuses. The difference between lakes and reservoirs--despite usually all called lakes--is pointed out.

Beyond discussing the definitions, as fluid as they might be, the lesson discusses the ways that many of these landforms have been created. This includes the weathering, erosion, and deposition of sediment by wind, water, ice (glaciers), and even gravity. The role that plate tectonics in oceanic and continental plate convergence--either convergent subduction or convergent folding--has in creating landforms such as mountains is shown.

While this lesson can be enjoyed by all audiences, it is designed to meet various standards of 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.

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.

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 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.

In this video we learn how to multiply fractions. Multiplying fractions is the easiest thing you can do with fractions so it's the first thing we'll learn.

http://www.rootmath.org | Algebra

In this video we learn that certain fractions are equal to 1. This will be very useful later when we want to find common denominators.

http://www.rootmath.org | Algebra

An introduction to adding fractions. We'll look at the easy case of adding fractions with a common denominator and we'll also see why we can't add fractions with different denominators.

http://www.rootmath.org | Algebra

In this video we find a least common denominator by first finding a Least Common Multiple. This technique is useful for 'small' or 'easy' numbers.

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 | Calculus

We use the chain rule to take the derivative of e^(2x).
