Errors in this video:

In the last 5 seconds of the video, the instructor calculates the cotangent of the angle using 6 as the denominator. The correct denominator would be 2. The cotangent of the angle reduces to 2 times the square root of 2. The instructor incorrectly writes it as 2/3 times the square root of 2.

Lesson Description:

Finding the six trigonometric functions from a triangle

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.
