well, just do
1 - cosθ = 1 + sinθ
sinθ = -cosθ
sin π/4 = cos π/4
So, in QII and QIV,
sin 3π/4 = -cos 3π/4
sin 7π/4 = -cos 7π/4
Find all points of intersection of the given curves. (Assume
0 ≤ θ ≤ 2π.
Order your answers from smallest to largest θ. If an intersection occurs at the pole, enter POLE in the first answer blank.)
r = 1 − cos θ, r = 1 + sin θ
