Find zeroes and factors of polynomials

In this example we use the  rational root theorem and synthetic substitution to find the zeros and factors of a polynomial to the third degree.

Verifying Trigonometric Identities 2

In this episode, there are 2 examples of verifying trig identities that I would rate on the more difficult side.  More advanced strategies are needed such as factoring and finding a common denominator.  While that sounds easy, it is often difficult to see when verifying trig identities.

Verifying Trigonometric Identities

In this episode, we look at verifying trig identities.  There are 3 examples that I would rate on the easier side.  You need to start somewhere.

What is a Podcast?

This podcast is not about math.  This is just a simple explanation of what a podcast is.  I have created this podcast to help my students learn more about podcasts.  They will eventually help me make more math podcasts.  I am very much so looking forward to this project.

Solve a quadratic equation by using substitution 2

Here is another example how to use substitution to solve a quadratic equation.  Now I know that there are other ways to solve this particular example (squaring both sides), but I wanted to show that substitution is a good way to solve a quadratic equation.
