Unit 8
Trigonometry

Objectives

After completing this unit, you should be able to

1. define “radian measure,” and convert freely between measurement by degrees and by radians.
2. characterize the basic trigonometric functions using the ratios of sides on a triangle.
3. characterize the sine and cosine functions as coordinates of the winding function.
4. use exact values when expressing the sine and cosine of key angles.
