## Homework Statement

I am having problems with these. Need some help please!

Here is a sample question I am having troubles with:

3 cos θ + 3 = 2 sin^2 θ, 0 <= θ < 2pi

I am really struggling with these. Any help would be great. What is my first step for solving a Trigonometric Equation using Identities ?

## The Attempt at a Solution

My teacher said you can solve this with a ti89 - But how would that be even possible? Just curious.

Thanks
