Problem
Two polar curves are given by
r1(θ)=3 and r2(θ)=2sinθ, with 0≤θ≤2π.
The region of interest is enclosed between the two curves and the rays θ=0 and θ=2π.
(a) Write a definite integral whose value equals the exact area of the region contained between the two curves on the stated interval. Do not evaluate yet.
(b) Evaluate the integral from part (a) to obtain the exact area. Express your answer in terms of π.
