Use a double integral to find the area of the region. The region inside the cardioid r = 1 + cos(θ) and outside the circle r = 3 cos(θ). Can someone explain to me where to get the limits of integration for θ? I get how to get the pi/3 and -pi/3 but most examples of this problem show further that you have to do more for the limits of integration but I do not get where they come from?
