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

r = cos 3θ, r = sin 3θ

i found that the curves cross when Theta =pi/12, but i'm having trouble finding which multiples to use
