## Explorations in Core Math Algebra 2 Chapter 11: Trigonometric Graphs and Identities - Chapter Summary and Learning Objectives

This chapter will help you analyze trigonometric graphs and identities. Lessons will explain how to graph a number of trigonometric functions and guide you to an understanding of various identities. You can focus on increasing what you know about:

• Graphs of the sine, cosine and tangent
• How to graph the cosecant, secant and cotangent
• Trigonometric, double-angle and half-angle identities
• Sum and difference identities
• Unit circles
• Trigonometric equations

Lesson Objective
