Ch 37: CEOE Middle Level/Intermediate Math: Trigonometry

About This Chapter

This chapter contains a lesson set used as preparatory for individuals taking the Certification Examinations for Oklahoma Educators (CEOE) Middle Level/Intermediate Math test. The subject of this chapter is trigonometry.

CEOE Middle Level/Intermediate Math: Trigonometry - Chapter Summary

These lessons are video presentations that act as a brush up before the CEOE Middle Level/Intermediate Math test. They will help you answer test questions on such lesson material as:

  • The sine and cosine in trigonometry
  • Ratios and similarity in trigonometry
  • Relating right triangles to sine and cosine by use of unit circles
  • Use of trigonometric function values for special angles
  • The definition and application of the law of sines and of the law of cosines
  • Using trigonometric equations to solve for X

The lessons delivered in this chapter are short, engaging videos, hosted by subject matter experts, and each ending with a quiz. If the quiz results in needing to relook at some part of the video, a timeline tool can be used to take you to the right spot in the video for restudy. Another tool will let you ask a question of the expert.

Trigonometry: Sine and Cosine

1. Trigonometry: Sine and Cosine

Learn an easy trick to help you solve trigonometry problems, including problems with sine, cosine and inverse trig functions. At the end of this lesson, you'll know what SohCahToa means and how to use it.

Trigonometric Ratios and Similarity

2. Trigonometric Ratios and Similarity

Where do terms like sine, cosine and tangent come from? In this lesson, we'll learn about how similarity with right triangles leads to trigonometric ratios.

Using Unit Circles to Relate Right Triangles to Sine & Cosine

3. Using Unit Circles to Relate Right Triangles to Sine & Cosine

The unit circle is a helpful tool for understanding trigonometric concepts. In this lesson, we'll look at right triangles on the unit circle to better grasp sine and cosine.

Trigonometric Function Values of Special Angles

4. Trigonometric Function Values of Special Angles

After watching this video lesson, you will better understand the six trigonometric functions. You will also know what special angles there are and what the trigonometric values for these special angles are.

Law of Sines: Definition and Application

5. Law of Sines: Definition and Application

Don't get stuck trying to find missing sides or angles in a triangle. Use the Law of Sines to rescue you from any perilous triangle in which you have just a few pieces of information.

Law of Cosines: Definition and Application

6. Law of Cosines: Definition and Application

In this lesson, we'll learn how to solve problems involving three sides and one angle in a triangle. The Law of Cosines, a modification of the Pythagorean Theorem, will save the day.

How to Solve Trigonometric Equations for X

7. 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.
