Question

what is {cscx/(1+cscx)}-{cscx/(1-cscx)}

Answer 1

Are you trying to simplify it?

Answer 2

yes haha forgot to put that

Answer 3

I can give you a computer generated solution, which shows it being equal to sin(x)^2-1

Answer 4

Oh, why do we need computers.

Answer 5

that actually helps. cause now i can work backwards

Answer 6

\[\dfrac{\csc(x)}{1 - \csc(x)} - \dfrac{\csc(x)}{1 + \csc(x)} = \dfrac{\csc(x) + \csc^2(x)}{1 + \csc^2 (x)} - \dfrac{\csc(x) - \csc^2(x)}{1 + \csc^2(x)}\]
