Lesson Summary:

In this lesson, you will learn how to find coterminal angles - two angles that share the same initial and terminal side. The instructor demonstrates using several examples, showing how to find coterminal angles by going clockwise or counterclockwise around the unit circle. He also mentions that sometimes there may be constraints on the coterminal angles, but in general, you can find them by adding or subtracting multiples of 360 degrees.

Lesson Description:

How to find coterminal angles using drawings

I show how to solve math problems online during live instruction in class. This is my way of providing free tutoring for the students in my class and for students anywhere in the world. Every video is a short clip that shows exactly how to solve math problems step by step. The problems are done in real time and in front of a regular classroom. These videos are intended to help you learn how to solve math problems, review how to solve a math problems, study for a test, or finish your homework. I post all of my videos on YouTube, but if you are looking for other ways to interact with me and my videos you can follow me on the following pages through My Blog, Twitter, or Facebook.
