# Ch 45: NMTA Math: Solving Trigonometric Equations

### About This Chapter

## NMTA Math: Solving Trigonometric Equations - Chapter Summary

This chapter of our NMTA Math study guide explores how to solve trigonometric equations. First, it helps you review the process of solving for X, a common feature of most trigonometric equations. But then, it will also help you recall the steps necessary for solving for identities and inverses, and the properties of these same inverse trigonometric functions. It will explore restricted domains and infinite solutions, too. By the end of the chapter, you will have reviewed:

- Solving for X in trigonometric equations
- Solving trigonometric equations with inverses and identities
- Inverse trigonometric functions: properties
- Trigonometric equations with restricted domains and infinite solutions

Each lesson has practice questions that will help illustrate how the NMTA Math exam will test your knowledge of these concepts. The practice questions are modeled on your upcoming exam. This gained familiarity will also help you budget your time.

### Objectives of the NMTA Math: Solving Trigonometric Equations Chapter

The computer-based NMTA Math exam tests your understanding of information across five domains. This chapter belongs to the trigonometry and calculus domain, which accounts for 19% of the 150 multiple-choice questions. The test is only 255 minutes long, so it is important to practice answering its questions through the use of our study guide.

### 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.
