Homework Statement
I have to find all of the points of intersection of the curves...
r2 = sin(2θ)
r2 = cos(2θ)
The Attempt at a Solution
sin(2θ) = cos(2θ)
2sinθcosθ = cos2θ - sin2θ
2sinθcosθ - cos2θ = -sin2θ
cosθ(2sinθ - cosθ) = -sin2θ
This is where I'm having a problem, I'm not sure what to do from here.
