Best ResponseYou've already chosen the best response.0If x is any angle, then a coterminal angle is x + any multiple of 2pi. So to find a coterminal angle in the range you're given, add/subtract multiples of 2pi to 5/8pi until you get one in range.

Best ResponseYou've already chosen the best response.0is subtracted and got 21pi/8. Is that right? Im kind of confused.

Best ResponseYou've already chosen the best response.011pi/8 is between 0 and 2pi so that's the angle you're looking for. Basically two angles are coterminal if they are the same when drawn; adding 2pi to an angle is essentially rotating in a full circle.

Best ResponseYou've already chosen the best response.0So for example, ..., 8pi, 6pi, 4pi, 2pi, 0, 2pi, 4pi, 6pi, 8pi, ... are all coterminal.
