We created a new video, called
Average Rate of Change. Average Rate of Change (AROC) is essentially the slope, but the video will teach the nuances of the concept and the calculations for AP Pre-Calculus students.

We have quizmasters that address the unit circle, but they focused on dergee measures. The new advanced placement pre-calculus program uses ONLY radians. So, those two quizmasters were adapted for radians. We still have the old quizmasters, of course. Here are the new ones:
Unit Circle: Radians and Ratios
Unit Circle: Radian Angles
All of the quizmasters are available at Trigonometric Angles: Unit Circle.
