Find the area of the region that lies inside both of the circles
r = 2sin(x)
r = sin(x) + cos(x)
A = (1/2)(int from a to b): r^2 dx
(I apologize because I do not know how to make calculus look proper in text form)
The Attempt at a Solution
What I need is some theoretical help. Through graphing these circles I can see that they intersect at pi/4. However, I see that they intersect near the origin, however I can not get a common angle, which makes me confused on how to set up the intervals of my integration. Any ideas to get me going would be much appreciated!
