Which ones differ by multiples of 2pi radians?
-4pi/3 + 2pi * k
k = 0 , -4pi/3
k = 1 , -4pi/3 + 2pi = -4pi/3 + 6pi/3 = 2pi/3
k = 2 , -4pi/3 + 4pi = -4pi/3 + 12pi/3 = 8pi/3
k = 3 , -4pi/3 + 6pi = -4pi/3 + 18pi/3 = 14pi/3
k = -1, -4pi/3 - 2pi = -4pi/3 - 6pi/3 = -10pi/3
k = -2 , -4pi/3 - 4pi = -4pi/3 - 12pi/3 = -16pi/3
