Question

How do I solve:
Find all polar coordinates of point P where P = (9,pi divided by 5).

(9, pi divided by 5 + 2nπ) or (-9, pi divided by 5 + 2nπ)

(9, pi divided by 5 + (2n + 1)π) or (-9, pi divided by 5 + 2nπ)

(9, pi divided by 5 + nπ) or (-9, pi divided by 5 + nπ)

(9, pi divided by 5 + 2nπ) or (-9, pi divided by 5 + (2n + 1)π)
