In Java exceptions are objects. The base for all exceptions is the Throwable class – it contains information about the cause of the exception, its description, and the stack trace. To raise an exception, you use the throw keyword. When an exception is thrown the program execution stops, and the execution travels over the stack until a matching catch block is reached to handle it.
Learn what are the main methods for exception handling and how to simplify your code construction.

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 | calculus 1

We get a feel for how we might take a derivative implicitly and we get the intuition of why implicit differentiation is really just uses the chain rule.

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

An introduction to related rates and an overview of the example problems to come

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

In this problem we related the rate of the rotation of a security beam to the rate at which the beam moves across the floor.

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

A more difficult problem involving the rate of change of a man's shadow as he walks away from a lamp post.

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

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

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 | Algebra

This is the second example of finding a least common denominator by first finding a Least Common Multiple. This technique is useful for 'small' or 'easy' numbers.

http;//www.rootmath.org
http://www.rootmath.org/calculus/properties-of-limits

We'll learn properties of limits (what we can and can't do with limits). We'll start to take these for granted in future videos when we solve limits.

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 | Linear Algebra

Vectors are added by adding corresponding components. Graphically we add vectors with a "head to tail" approach.

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

Another example of using critical numbers to help us gain a deeper understanding of the relationship between a function and it's derivative

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

Another example of using critical numbers to help us gain a deeper understanding of the relationship between a function and it's derivative

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

Same chain rule, different notation. We'll look at a popular way of viewing the chain rule.

http://www.rootmath.org | Calculus

This is a more advanced example of using the chain rule. In this video we need to use the chain rule twice in a row in order to find the complete derivative. Don't let the title fool you, its not difficult, its just a more advanced example that you should know how to do!

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

We now learn how the product rule and chain rule can take the place of the quotient rule.

Successful communication in a culturally diverse environment requires knowledge and understanding. Our video suggests ways to communicate effectively in a culturally diverse workplace. #culturaldiversity #diversity #culturalawareness #interculturalcommunication #simpleshowfoundation #explainervideos

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

We learn how to take the derivative of a product by using the product rule.

http://www.rootmath.org/calculus/continuity-and-one-sided-limits

Continuity is a requirement for many theorems, we'll look at how it is defined.

http://www.rootmath.org
http://www.rootmath.org/calculus/continuity-and-one-sided-limits

An example of forcing a piece-wise function to be continuous.

Proof of the lim(sinx/x) = 1

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

A look at the geometry of a limit we looked at previously.

http://www.rootmath.org | Calculus

In this video we discover the derivative by attempting to find the slope of a tangent line. We'll see that the derivative is just a limit involving slope.

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.

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!

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.

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!!

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.

Graphing y = sinθ and y = cosθ using the unit circle and knowledge that we have about sine and cosine ratios.
Please note that the last example is actually on page 363 not page 360 : )

Clear explanations of the various possible transformations to trigonometric functions. f(x)=sinx f(x) = cos x
f(x) = a sin [k(x-d)]+c
Stretches, compressions, shifts, where to find the equation of the axis and how to determine the period of the function.
