# Ch 56: MTEL Math: Trigonometric Identities

Trigonometric identities are the focus of this chapter. Numerous video lessons will bring to mind the information you've learned already. Use your refreshed knowledge to help you answer related MTEL Math examination questions at the appointed time.

## MTEL Math: Trigonometric Identities - Chapter Summary

The video lessons in this chapter will show how some identities can assist you in solving complex equations. These animated lessons can re-introduce you to the different types of trigonometric identities and remind you of their various uses. Discover how expressions and equations can be organized through the use of the Pythagorean identities, and recall the rules for writing half-angle identities or rewriting functions altogether. After viewing each of the lessons, you could:

• Understand the uses for trigonometric identities
• List trig identities that include sin and cos
• Identify alternate trig identities
• Describe the applications for Pythagorean identities
• Discuss the uses for sum-to-product, half-angle, product-to-sum, double-angle and reciprocal identities
• Prove a trigonometric equation identity
• Use sum and difference identities, and derive trig identities

Learn from accomplished instructors whose goal is to make it easy and fun to conquer these mathematical concepts. The chapter's video lessons are short and designed to fit into your schedule. They include graphics and narration along with several examples that you can go over multiple times as you strive to become an expert on trigonometric identities. Before taking on the MTEL Math examination's related questions, complete this chapter's short quizzes.

### MTEL Math: Trigonometric Identities Chapter Objectives

The five multiple-choice subareas on the MTEL Math examination include several sub-sections. Subarea V is titled Trigonometry, Calculus and Discrete Mathematics. It has 19 - 23 objectives, between 19 and 21 multiple-choice questions, and a 16% share of the test weighting. During its first sub-section, demonstrate your knowledge of the properties of trigonometric identities and the law of sine and cosine among other topics while going for a teaching license. Set aside four hours to answer the computerized certification examination's 100 multiple-choice questions and two open-response items.
