# Unit Circle (A Walk-through)

Part 1: Fill out the angles in radians and degrees
Part 2: Fill out the coordinates using special triangles (45-45-90 and 30-60-90)
Part 3: Patterns in the unit circle regarding radians and exact values
Part 4: How the radius being one in the unit circle simplifies evaluating trig functions. Sinx=y, cosx=x, tanx=y/x and so on.
