i m having problems integrating this:

(integral) tanxcscx

i m pretty sure u gotta multiply it by a one, like a secx/secx or something i cant figure out what to mulitply it by to integrate it.

and also i m having problems with this

2x^3-7x^2+7x / 2x-5

u gotta divide these out, i m pretty sure i m getting wrong answer.. any helpp appreciated.!
