sin(theta) = -1
:
the first occurrence of theta is -90(measuring clockwise) which is equivalent to 270(measuring counter clockwise)
:
the answer assumes the angle is being measured counter clockwise
:
if you used the -90 direction, then you have
:
(2 * pi * n) - (pi/2), for n = negative integers, 0, positive integers(the set Z)
