To determine the angles at which the curves r1(θ)=2+2sin⁡θr_1(\theta)=2+2\sin\theta and r2(θ)=3sin⁡θr_2(\theta)=3\sin\theta intersect, which of the following equations should be solved for θ\theta? (a) (2+2sin⁡θ)2=(3sin⁡θ)2(2+2\sin\theta)^2 = (3\sin\theta)^2 (b) 2sin⁡θ=3sin⁡θ2\sin\theta = 3\sin\theta (c) 2+2sin⁡θ=3sin⁡θ2+2\sin\theta = 3\sin\theta (d) 2+2sin⁡θ=32+2\sin\theta = 3
