***
-600º
Starting from the initial standard position of zero, rotate clockwise 360º+240º, which places the reference angle of 60º in quadrant II. (240-180=60º)
..
7π/4
Starting from the same initial position, rotate counter clockwise π+ (3/4) π, which places the reference angle of π/4 in quadrant IV. (8π/4-7π/4=π/4
