The question is to find the area of the region that lies inside both curves. The part I'm specifically having trouble with is finding the points of intersection.

2. Relevant equations

sin (2∅)

cos (2∅)

3. The attempt at a solution

sin 2∅ = cos 2∅

2 sin ∅ cos ∅ = 1 - sin^2 ∅

2 sin Θ cos Θ + sin^2 Θ = 1

sin Θ(2cos Θ + sin Θ) - 1 = 0
