Simplify tan(540-theta)

In the unit circle do I have to go clockwise or anti-clockwise from the fourth quadrant?

Please help is needed for this

**Steve**, Tuesday, May 22, 2012 at 9:38amSince 540 = 3*180

and the period of tan(x) is 180

tan(540-x) = tan(-x) = -tan(x) = -1/5

However, to answer your question, yo need to go clockwise, since you have tan(-x).
