Question

Can someone explain to me how to find out if this is an identity or not?

Sorry, I don't know how to

Answer 2

Unfortunately, I do not believe this is something you can prove. When expanding you start with:

\[(sinx+cosx)/sinxcosx\]

From this, you can see that you cannot remove sinx or cosx for they would have to be in one expression. Even if you tried to square the equation you would get nowhere. This is not an identity.
