Start by factoring the equation and using the Zero Product Property. Then, draw the unit circle on the coordinate plane.

radians, radians, radians, radians

Practice makes perfect

To solve the given equation, we will first factor it and use the Zero Product Property to solve for Then we will use the unit circle to find the exact values of that satisfy the equation.

Solving the Equation for

Let's start by rewriting the equation so that all of the terms are on the left-hand side, so we can factor it.
Next, we can use the Zero Product Property to solve the equation for
Solve for
