1. The problem statement, all variables and given/known data Find the area of the region that lies inside both of the circles r = 2sin(x) r = sin(x) + cos(x) 2. Relevant equations 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) 3. 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!
