About This Lesson
http://www.freemathvideos.com In this video series I show you how to solve trigonometric equations with multiple angles. We solve these equations in the same manner that we solve equations with one angle in that we learn to isolate our trigonometric function by either using inverse operations or factoring to use the zero product property. We then evaluate our trigonometric function for our multiple angle just like we would if it was a single angle. Depending on the problem we will evaluate on a interval of [0,2pi) or all real solutions. We then solve for our variable by using inverse operations.
