Working with the Unit Circle - Part 3

This video is the last part (of three) that explains how use the basics of the unit circle to answer many types of questions. You will find the exact values of sin, cos, and tan if given an angle or point, and also find the exact coordinates of (x, y) if given an angle. Finally, you will see how to find the missing coordinate of (x, y) if you know either x or y.
