Make the sub:
1. The problem statement, all variables and given/known data
Solve for θ.
2sinθcosθ + 1 - 2sin^2θ = 0
2. Relevant equations
No equations, just identities.
3. The attempt at a solution
I tried factoring, but I don't know how to continue with 2 diff ID's in one equation.
I don't know how to simplify it so that everything is in terms of one similar Identity.
