Chapter 1 – Unit Circle and Definitions

Topic 1.5
Properties of Trig Functions

Properties of Trig Functions expands the special unit circle values from 0 to 2π to include angles larger than 2π and negative angles. By the end of the lesson, students should be able to find the sine and cosine values for arbitrarily large angles. Information about the quadrant an angle is in should allow students to find these values having only memorized the unit circle from 0° to 90°.
