if this is chapter 4 or 5 and I remember right don't you just add the 2pi and continue around the circle?
OpenStudy (anonymous):
If you have a negative point on the unit circle, add 2pi until you get a positive number. Then, for positive values, take out multiples of 2pi For example: \[ \frac{ 15\pi }{ 7} =2\frac{ \pi }{7 } \rightarrow \frac{ \pi }{7}\]
