- Homework Statement
- 3.44(cos^2 (theta)) - 25 sin(2 * theta) = -19.62

- Relevant Equations
- cos ^2 theta = cos theta times cos theta

sin (2* theta) = sin theta times cos theta times 2

I’m stuck on how to begin. I’ve tried to factor out sin theta from both of the terms on the left hand side but that led to nowhere. Could I have a hint on how to continue? Than you!
