Coterminal Angles

I need help with this.. it's for my midterm review. My midterm is next week. I would appreciate the help.

Determine two coterminal angles (one positive and one negative) for each angle. The answer must be in degrees.

a) 36 degrees
b) -120 degrees
c) 300 degrees
d) -420 degrees

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

    so 36ΒΊ + 360ΒΊ = 396ΒΊ
    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.

  3. 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.

  9. so I have the conterminal angle of 111 degree. So do I add and subtract with 360 degree or 180 degree?
