I have to find all of the points of intersection of the curves...

r^{2}= sin(2θ)

r^{2}= cos(2θ)

3. The attempt at a solution

sin(2θ) = cos(2θ)

2sinθcosθ = cos^{2}θ - sin^{2}θ

2sinθcosθ - cos^{2}θ = -sin^{2}θ

cosθ(2sinθ - cosθ) = -sin^{2}θ

This is where I'm having a problem, I'm not sure what to do from here.
