Double Integration in Polar coordinates:
1) Find the area of the region cut from the first quadrant by the curve r= 2(2 - sin 20).
2) Find the area of the region that lies inside the cardioid r= 1 + cos 0 and outside the
circle r = 1.
3) Find the area enclosed by one leaf of the rose r= 12 cos 30.
4) Find the area of the region common to the interiors of the cardioids r = 1 + cos 0 andr=
1 - cos 0.
5) Find the area enclosed by the circle r= 3 cos 0 and the cardioid r = 1 + cos 0.
