This is the problem. The question is simple i just need some clarification as indicated on the part highlighted below in red.

Now from my understanding tangent repeats on a cycle of ##π## radians...why do we have 2 the part circled in red below i.e ##2##? This is the part that i need clarity. Why consider cycles for sine and cosine here?

It's straightforward and less stressful to just use ##π##radians in my opinion.

The other form given below is the one that i know and am very much conversant with;
