never mind guys... I found it.
For those who want to know, just put everything under a common denominator. Then convert cot^2(x) + 1 to csc^2(x). Then factor, and it will cancel.
Hey guys, this problem has been racking my brain for around an hour. I guess I'm just having a brain fart, as it should be easy. Either way, here it is:
This should simplify out to csc(x). Could anyone explain how that happens?
Thanks in advance.
