If tan theta= 1/5
Simplify tan(540theta)
In the unit circle do I have to go clockwise or anticlockwise from the fourth quadrant?
Please help is needed for this

Maths 
Steve,
Since 540 = 3*180
and the period of tan(x) is 180
tan(540x) = tan(x) = tan(x) = 1/5
However, to answer your question, yo need to go clockwise, since you have tan(x).
