Thread: Trig functions

What's the question, find f(x)?

I'm going to assume that is the case. Recall that:
cos(-x) = cos(x)
sin(-x) = -sin(x)
tan(-x) = -tan(x)

This is the same for their reciprocals. Knowing this, we reach here:



Combine sin(x) with the fraction to get:


Can you continue now?

No...I don't know how to break that into something more simple
