5 9. 15 a) Make a sketch of the polar curves r = 3 sin 0 and r = 1 + sin 0 on the same coordinate system. Label which curve is which. b) Find the angles 0 at which the curves intersect. c) Set up, but do not evaluate, an integral, or integrals, that gives the area inside both of the curves r = 3 sin 0 and r = 1 + sin 0. DO NOT EVALUATE THE INTEGRAL(S)
