1. ### Find the area of the region enclosed by the inner loop of the curve.  r = 6 + 12 sin(θ)?

Let r = 0 6 + 12sin(θ) = 0 sin(θ) = -1/2 In one cycle,θ = 7π/6 or θ = 11π... of integration. The radius is negative through that interval, but r will be squared, so that is not an issue. area = ∫[7π/6,11π/6...
