Find all points of intersection of the given curves and

Question

1. Find all points of intersection of the given curves. (Assume 0 ≤ θ ≤ 2Π and r ≥ 0. Order your answers from smallest to largest θ. If an intersection occurs at the pole, enter POLE in the first answer blank.)

r = sin(θ), r = sin(2θ)

(r, θ) =
(r, θ) =
(r, θ) =

2. Find the exact length of the polar curve. r = θ², 0 ≤ θ² ≤ Π
