  1. adding or subtracting multiples of 360º to any angle will result in the rotating arm ending in the same position, thus giving you "coterminal" angles

    so 36º + 360º = 396º
    36 - 360 = -324

    so that to each of your angles.
    (for -420 you will have to add 720 to obtain a positive result)

  2. Thx! I really do understand it now. What if they give me like pi/9.... How do i find two coterminal angles (one positive and one negative) in RADIANS.

  4. 360 degrees is 2 pi radians so adding or subtracting 2 pi (or a multiple of 2 pi) to an angle in radians brings you to the same place.
