Question 611301: Given than costheta=-1/2, determine the value(s) of 'theta' over the interval [0degrees, 360degrees].
I am not really sure what the question is asking for, so therefore I haven't really had much to go off of to try much. I do not know what they mean by 'interval', so that confuses me in this situation.

cos(x) = -1/2

x = arccos(-1/2)

x = 120 or x = 240
