Unit Circle and Radians

Measure angles is easy as pi. Pupils review special right triangles to find exact values for trigonometric functions. Scholars learn about radians and how they connect to measurements in degrees. They find exact and approximate values of trigonometric functions using angles measured in degrees and radians.
