I wish I knew how to use the Latex:

Sec^2(x)Csc^2(x)=Sec^2(x)+Cot^2(x)

I have tried to work with both sides of the expression at different times and looked at the work on each side to determine if I could get the solution,

I have left the left side alone and changed the right side to be

= Sec^2(x) + (csc^2x-1) But I get stuck.

Any help with the side and which I should change would be great.

Thanks
