Errors in this video:

At about the 50 second mark, he states and labels the top of the unit circle as pi over 4, when it should actually be pi over 2. He also labels the point on the left as 4/4 when it should have been 4 pi over 4. At about the 2 minute mark, he says "6 over 6 pi" when he should have said "6 pi over 6".

Lesson Summary:

This lesson teaches how to find a point on the unit circle given a real number. The key is to break the number down into fractions and then use the unit circle to find the point. By understanding how to break down the numbers into fractions and using the unit circle, you can easily find any point on the circle.

Lesson Description:

How to find the point on the unit circle from the given real number

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.
