I am trying to prove that the equations below equal each other.(adsbygoogle = window.adsbygoogle || []).push({});

## (cscθ - cotθ) = (cscθ + cotθ)^{-1} ##

Besides letting the two sides equal each other, I have not been able to simplify each side independently to find the equivalent expression. I've had to remove terms from either side by multiplying each side simultaneously, but if anyone could show me how to do this proof one equation at a time, then that would be great!
