Or, for access to this single video, go to: http://www.mindbites.com/lesson/1215-pre-calculus-solving-trig-equations-by-factoring Professor Burger teaches how to solve more complicated equations (tanx * sin^2x = tan x) involving trigonometric functions in this lesson. Solving these types of problems involve use of trig identities, factoring, etc and how to find all of the viable solutions for these types of problems. In the problem listed above, Professor Burger will show you how to factor the equation in order to help simplify and then solve it. Professor Burger also gives a warning about cancelling out in equations that involve trig functions. By canceling, you risk missing valid solutions and solution sets. Taught by Professor Edward Burger, this lesson was selected from a broader, comprehensive course, Precalculus.
