This chapter will build on the trigonometry you learned in Chapter 9 while you continue to find increasing complex solutions to trigonometric equations. 3 new ratios, secant, cosecant and cotangent are introduced. Using the unit circle, you will be able to justify the number of solutions to trigonometric equations. In addition, you will use trigonometric identities to solve equations.

Checkpoint Review: Students master different skills at different speeds. No two students learn exactly the same way at the same time. At some point you will be expected to perform certain skills accurately. Most of the Checkpoint problems incorporate skills previously developed. Each chapter has a different skill that should be mastered.
