    Integral help

    I don't know how to use the codes, so you will have to bear with me a little

    Integrate

    (cot x)^2 dx

    Everything I tried just doesn't work. I am not sure what trig identity to use to get to the answer.

    Thanks for the help

    Use   1- csc^{2}x = cot^{2}x



    OR you can use the suggestion above.
