Find an expression for :
csc^2 (tan^-1 (3/x))
in terms of x
Note, I edited my original post because I messed up on the final line. So if you already looked at it, look again. It's fixed now. That should be the expression you're looking for.
- BTW, this kind of question probably should have been posted in the trignometry section, since these are inverse trig functions.
