9. Chapter 7: Trigonometric Equations and Identities

This creates an equation that is a polynomial trig function. With these types of functions, we use algebraic techniques like factoring, the quadratic formula, and trigonometric identities to break the equation down to equations that are easier to work with. As a reminder, here are the trigonometric identities that we have learned so far:
