1. The problem statement, all variables and given/known data find the area inside both of the curves r = 4 cos@ r = 2+2cos@ @ = theta 2. Relevant equations ------- 3. The attempt at a solution i will say 4cos@ = 2+2cos@ to find the intersection points 4cos@ = 2+2cos@ 2cos@ = 2 cos@ = 1 @ = 0 !! I need the other points!!
