Yes, most likely, if you would post a problem.
You need to know your formulae and apply them to solve your proof problem. The thing is to 'see' how to solve it. Don't worry, it'll come with practice.

I believe it is.
Change the cot(x) on the left in the denominator to
Then, simplify and factor a little. You will see another 1+sin(x) terms and they will cancel.
The tan will reveal itself as
