I guessing you meant

with cot instead of cos. If I am wrong then you will have to re-post your question.

One of the Pythagorean identities is . Using this we can substitute in for :

The cot's cancel:

One of the Reciprocal identities is that sec and cos are reciprocals of each other. So:

is equal to:
