Can someone help me with solving this identity?

cotx = cscx + 1
----- -----------
cscx - 1 cotx

I see what it is?:

\frac{cot(x)}{csc(x)-1}=\frac{csc(x)+1}{cot(x)}

Multiply the top and bottom of the left side by

csc(x)+1

It will transform into the right side.


Does this even matter? If you're not going to respond back to make sure I have the correct set up or anything, why bother at all.?.

Maybe I am being petty, but it gripes me when someone posts a problem, then never responds back whatsoever. What's the point? In this one, the post got garbled and they didn't even bother to try and straighten it out.
