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

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)

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.

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.

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