Introduction to the Unit Circle

In this video, you'll learn why the unit circle is called the unit circle, what a reference angle is, and how to draw reference angles on the coordinate plane aka the x-y plane.

I'll cover key vocab such as unit circle, reference angle, terminal side, standard position, and quadrants.

If you visit the site, I also have a free downloadable version of the Unit Circle you can (and should) print out.
