Homework Help: Trig Limit

  1. May 17, 2010 #1
    For some reason, I'm having trouble with the following:

    limit as x-->pi/2 (cot^2(x))/(1-csc(x))

    Any help would be appreciated!

    I would multiply by 1 + csc(x) over itself. Keep in mind the identity that involved cot^2(x) and csc^2(x).
