Question

Find the area of the region that lies inside both curves: r=sin2θ r=cos2θ

Answer 1

Do you know the formula for area enclosed?
This is calculus am I right?

Answer 2

Yes with polar coordinates. the formula is 1/2 the integral from a to b [(f(θ))^2-(g(θ))^2]dθ

Answer 3

\[\int\limits_{a}^{b} f(θ)^{2}-g(θ)^{2}dθ\]
