Prove that sec^(2)x - cosec^(2)x is equivalent to tan^(2)x-cot^(2)x.

I always end up with some really complicated identity and can never get te LHS to equal the RHS. Does anyone know a method for solving trig identities? I feel like mine always end up going on forever and never getting the right answer

Thanks in advance!

There are standard (formula book) identities that should make this question quite easy. Do you know what I'm referring to?

Or are you not allowed to use these identities?

For this question, focus on only the LHS. I can send a photo of the solution if you want?
