Who do you find the primary coterminal angle of an angle that's in radians?

well if you replace pi with 180, and do the algebra out, you find out that it is representing the angle 617.1 degrees. you can then divide that by 360 to find out how many times around a circle that it. (about 1.714) the 1 is irrelevant because if you go around the circle once, ur in the same place, so u inly look at the .714. (.714*360=257.04 degrees) that is where you are on the circle.. or -42.96
