In this video, we graph rational functions where the numerator has the same degree as the denominator.

In this video, we solve exponential equations by rewriting the exponential terms so that they have the same base.

In this video, we solve more exponential equations by rewriting the terms so that they have the same base.

In this video, we solve three questions (in order of ascending difficulty) where we solve exponential equations by using logarithms.

In this video, we learn a method for calculating the inverse of a matrix.

Find all six trig ratios given a point on the terminal side of theta. In this video we work this common type of problem. We use the Pythagorean Theorem to find "r" (hypotenuse), and then use the given "x" (adjacent) and "y" (opposite) to...

In this video, we solve rational equations by finding a common denominator.

In this video, we learn how to solve quadratic equations with the quadratic formula. We examine one example where we have to simplify the radical, and a second example with a nonreal solution.

In this video, we define radians and learn how to convert between radians and degees.

How do you solve equations with radicals? How do you solve equations with more than one radical, or with radicals on both sides? This video includes two examples of how to solve this type of problem.

How do I solve trig equations using the unit circle? Sometimes, we can solve sine and cosine equations without a calculator. To do this, we just have to reference the unit circle. This video solve four examples.

How do you solve trig equations that have something squared in them? In this video I show how to use a U-substitution to rewrite trigonometric equations as quadratics, which makes them easier to solve. We use the unit circle to solve...

How do you solve trig equations with the values are not on the unit circle? When your solving results in decimals, you can the inverse trig function in the calculator to find the solution. Then, use reference angles to find he other...

This is the first of two videos on solving systems of equations using the substitution method. Make sure to watch "Solving Systems by Substitution 2" for help with solving systems when both equations are in standard form!

Find all six trig ratios given a point on the terminal side of theta. In this video we work this common type of problem. We use the Pythagorean Theorem to find "r" (hypotenuse), and then use the given "x" (adjacent) and "y" (opposite) to...

In this video, we solve quadratic equations by factoring and using the zero product property. The first example has us factor a quadratic with a leading coefficient of 1, and the second video has us factor a quadratic with a leading...

In this video, we write equations in slope intercept form by starting with point-slope form.

This video highlights the top 10 countries that do the best job of preventing extreme wealth from collecting at the top. Countries like Hungary, Belgium, and Japan use government programs, fair wages, and smart tax policies to keep...

In this video, we develop a program that will continue to prompt the user to enter a number until a zero has been entered.

Welcome to our complete high school mathematics tutorial series! Whether you’re a student preparing for exams, a teacher seeking additional resources, or a parent helping your child succeed in math, these videos cover a wide range of...
