The discussion focuses on finding the area of the region that lies inside both curves defined by the equations sin(2∅) and cos(2∅). The key challenge is determining the points of intersection between these two trigonometric functions. The solution involves manipulating the equations to find a single equation using the tangent function, specifically by dividing the first equation by cos(2∅). This approach simplifies the problem and leads to the necessary points of intersection.

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.
Homework Equations
sin (2∅)
cos (2∅)
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
