### About This Chapter

## OAE Mathematics: Solving Trigonometric Equations - Chapter Summary

Decipher the different trigonometric functions as you go through these engaging video lessons. Practice all the techniques involved in solving trigonometric equations. Since a whole section of the OAE Mathematics test is dedicated to trigonometry and calculus, you will most likely have to know the procedures for solving these types of problems. By the end of this chapter, you should possess a deeper comprehension of the following:

- Solving for X in trigonometric equations
- Inverses and identities
- Restricted domains
- Inverse trigonometric functions
- Equations with infinite solutions

You can watch these video lessons on practically any device, including your phone, tablet, laptop, or computer. User-friendly controls let you move between topics easily, and you can watch the lessons as many times as you need to learn the information. Written transcripts accompany each lesson, and they can be used as your own personal set of notes for quick review.

### OAE Mathematics: Solving Trigonometric Equations Chapter Objectives

Ohio uses the OAE Mathematics test as part of the educator licensure process. This computer-based test takes 255 minutes to complete, and test-takers are responsible for answering 150 multiple-choice questions.This test covers five major areas of study in mathematics, including trigonometry and calculus topics. This section makes up 19% of the test, and the lessons in this chapter will walk you through the steps for figuring out these types of math problems.

### 1. How to Solve Trigonometric Equations for X

Adding trigonometric functions into standard algebra equations adds complexity. Learn how to solve trigonometric equations for x and how to use inverse operations to simplify equations.

### 2. Solve Trigonometric Equations with Identities & Inverses

After watching this video lesson, you will be able to solve trigonometric equations by making use of trigonometric identities and inverses. Learn the steps to take to get to your solution.

### 3. Properties of Inverse Trigonometric Functions

After watching this video lesson, you will understand why our inverse trigonometric functions have a limited range. Learn what this does. Also learn the notation for these functions.

### 4. Solving Trigonometric Equations with Restricted Domains

After watching this video lesson, you will be able to find the right answer for a trigonometric equation with a restricted domain. Learn what it means to have a restricted domain and what you need to do to find your answer.

### 5. Solving Trigonometric Equations with Infinite Solutions

Watch this video lesson and you will learn that all trigonometric equations have an infinite set of solutions. But you will also see that we can still go ahead and solve our equations and find concrete answers.
