Chapter 4
Chapter 4 returns students to trigonometric functions first introduced in Geometry. Students will convert between degrees and radians, set up the unit circle, expand on the definitions of sine, cosine, and tangent as well as recall special right triangles. Students will practice problem solving with angles of depression or elevation and solve functions with any angle. After the midchapter, graphs will dominate as we look at sine and cosine graphs as well as a little time with other functions. The chapter ends with inverse functions and applications of trigonometric functions.
