### About This Chapter

## CEOE Advanced Math: Trigonometric Applications - Chapter Summary

Get another look at trigonometric applications before you sit for the CEOE Advanced Math exam. The lessons in this chapter take a look at the principles and formulas involved in various trigonometric applications. They provide you with an effective and efficient review of the following:

- Oblique triangles and the law of cosines
- Utilizing the law of cosines when working with triangles
- The addition and subtraction formulas for tangent, cosine and sine

You'll have the chance to check your progress with a practice quiz at the end of each lesson, which will also serve as a way to familiarize yourself with the sorts of questions you may encounter on the exam. If you want to study further offline, each quiz can also be printed as a worksheet.

### CEOE Advanced Math: Trigonometric Applications Chapter Objectives

The CEOE Advanced Mathematics exam is a required component of the teacher certification process in Oklahoma for those going into the instruction of advanced math. The exam is composed of 80 multiple-choice questions spread across five subareas as well as one constructed-response assignment that pertains to the relations, functions, and algebra subarea.

Studying this chapter will be useful for passing portions of the trigonometry and calculus subarea, which as a whole comprises 23% of the exam's content. You can use these lessons to make sure you don't miss a beat on questions related to trigonometric applications.

### 1. Solving Oblique Triangles Using the Law of Cosines

After watching this video lesson, you will be able to use the law of cosines to help you find a missing side or missing angle of any kind of triangle. Also, you will see what oblique triangles are.

### 2. Solving Real World Problems Using the Law of Cosines

After watching this video lesson, you will be able to use the law of cosines to solve real-world problems. Learn what kinds of real-world problems the law of cosines can help you solve.

### 3. Using the Law of Sines to Solve a Triangle

After watching this video lesson, you will be able to use the law of sines to find a missing side of a triangle as well as a missing angle of a triangle. Learn what you need to know about the triangle in order to use the formula.

### 4. Solving Real World Problems Using the Law of Sines

After watching this video lesson, you will be able to use the law of sines to solve problems that you will encounter in the real world. Learn what kind of shape you need in order to solve your real world problems.

### 5. Proving the Addition & Subtraction Formulas for Sine, Cosine & Tangent

Watch this video lesson, and you will see how the angle sum and difference identities are derived for sine, cosine, and tangent. You will also learn how you can use these identities to help you solve problems.
