About This Lesson
http://www.freemathvideos.com In this video series I show you how to solve trigonometric equations by isolating the trigonometric function and finding the values for that function at it's given value. For these problems we are evaluating the trigonometric term for multiple angles. Once we solve for our function we will then solve for our variable. Since we have infinite many angles we leave our answers in terms of infinite coterminal angles.
