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

Trigonometry and calculus questions account for 19% of your AEPA Math certification assessment score. Use this chapter to review the trigonometric equations you'll likely encounter on the test.

The remaining four content domains on the AEPA Math assessment are as follows: measurement and geometry (19%); statistics, probability and discrete mathematics (19%); mathematical processes and number sense (19%); and patterns, algebra and functions (24%). There are 150 multiple-choice questions in total on the computer-administered exam. You'll have four hours and fifteen minutes to answer them all.

### 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.
