# Ch 44: NES Math: Trigonometric Graphs

### About This Chapter

## NES Math: Trigonometric Graphs - Chapter Summary

This chapter's lessons offer a review of graphs and explores their use in trigonometry. As you study for the NES Math test, you can use this part of our study guide to find out more about:

- Graphs of sine and cosine transformations
- Graphs of the tangent function
- Graphs of the secant, cosecant and cotangent functions
- How graphs can show trigonometric identity
- How to solve a trigonometric equation through a graph

These videos are short, averaging about five minutes in length, and our instructors use humor and examples to keep them lively. You can watch on a computer or mobile device from anywhere you have an Internet connection. Lesson quizzes let you assess your learning. The written transcripts feature important concepts and terms in bold type, and there is a sheet of quiz questions you can print and use for offline study.

### NES Math: Trigonometric Graphs Chapter Objectives

Five states make passing the NES Math test a requirement for obtaining teacher certification in math at the secondary level. The test's questions are divided into five content domains, and questions on trigonometric graphs are in the Trigonometry and Calculus content domain. This part of the test accounts for 19% of the total score.

There are 150 multiple-choice questions on the NES math test. You'll be required to read a question or solve a problem and choose the correct answer from several options. Our lesson quizzes are in this same format, so completing them will give you a preview of what you'll face on test day.

### 1. Graphing Sine and Cosine Transformations

What happens when we take the sine and cosine wave and transform them? They get bigger, smaller, faster and slower. Find out how in this lesson on sine and cosine wave transformations.

### 2. Graphing the Tangent Function: Amplitude, Period, Phase Shift & Vertical Shift

Take a look at how the graph of a tangent function and how we can transform it by making a few small changes to its equation. This video shows how to graph the original function and explains its transformations.

### 3. Graphing the Cosecant, Secant & Cotangent Functions

After watching this video lesson, you will learn what the graphs of the cosecant, secant, and cotangent trigonometric functions look like. You will also learn how to see if these graphs are shifted or transformed.

### 4. Using Graphs to Determine Trigonometric Identity

After watching this video lesson, you will be able to use graphs to determine whether an equation is a trigonometric identity or not. Learn what you need to look for to determine this.

### 5. Solving a Trigonometric Equation Graphically

How can you show someone that you have the right answer? This video lesson will show you how you can do this for a trigonometric equation. Learn what you need to watch for and how to get your answers.
