About This Lesson
http://www.freemathvideos.com This math problem was filmed during online live instruction for class. This is my way of providing a free tutorial for students that want to learn math from an online tutor. Please visit my website listed above where you can view all of my math lessons. 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 live classroom. These videos are intended to help you learn how to solve math problems, review how to solve math problems, study for a test, finish your homework and get a better grade in your math class. Please write to me and let me know how I can better help you! http://www.freemathvideos.com In this video series I will show you how to simplify a trigonometric expression by factoring and then simplifying. We will use factoring techniques such as grouping, difference of two squares, ac method, and perfect squares. Once we have an expression factored we will then use our trigonometric identities to simplify our expression to a single trig function or value. We will use trigonometric identites such as Pythangorean, even/odd, reciprocal, quotient, and co-function.
