# Ch 45: WEST Math: Solving Trigonometric Equations

### About This Chapter

## WEST Math: Solving Trigonometric Equations - Chapter Summary

Re-discover the rules for solving trigonometric equations by reviewing the online video lessons in this chapter. Review what you've already learned about graphing sine, cosine and tangent functions. Your knowledge of these and other topics can help you pass the WEST Math examination. The information in this chapter can assist you with:

- Simplifying equations with inverse operations and solving equations for x
- Demonstrating the notation for inverse trigonometric functions
- Using trigonometric identities
- Solving trigonometric equations that have infinite solutions or restricted domains

The video lessons in this chapter are designed to serve as a study resource that helps prepare you for the WEST Math examination. Led by experienced instructors, the lessons consist of video tags that let you re-watch lessons. They also include corresponding text transcripts. After watching the lessons, take the quizzes and the practice chapter examination to assess your progress.

### 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.
