Best ResponseYou've already chosen the best response.0Cant you find the middle point? Then solve using two integrals?

Best ResponseYou've already chosen the best response.0I mean they should intersect at pi/6 ( where they have the same value) > unit circle I believe ( I don't remember so much)

Best ResponseYou've already chosen the best response.0Yeah and then integrate both int ( pi/6  sinx ) + int ( cos x  pi/6) no? Yeah I'm taking cal II too ( well in quebec, might be different curiculum)

Best ResponseYou've already chosen the best response.0so you'll need to split the integral up

Best ResponseYou've already chosen the best response.0so you need the intersection point

Best ResponseYou've already chosen the best response.0the reason why you need two? If you do high  low , they switch at the intersection

Best ResponseYou've already chosen the best response.0\[ A = \int_y\int_xdxdy=\left[\int_{x=0}^{\pi\over4}\int_{y=0}^{\sin x}+\int_{x={\pi\over4}}^{\pi\over2}\int_{y=0}^{\cos x}\right]dxdy\\ A_1 = \int_{x=0}^{\pi\over4}\left[\int_{y=0}^{\sin x}dy\right]dx=\int_0^{\pi\over4}\sin x\,dx=1{1\over\sqrt{2}}\\ A_2= \int_{x={\pi\over4}}^{\pi\over2}\left[\int_{y=0}^{\cos x}dy\right]dx=\int_{\pi\over4}^{\pi\over2}\cos x\,dx=1{1\over\sqrt{2}}\\ A=A_1+A_2=2{2\over\sqrt{2}}\\ A=2\sqrt{2} \]
