Homework Help: Evaluate integrals using modified Bessel function of the second kind

  1. Oct 20, 2012 #1
    Hi guys,

    I encountered it many times while reading some paper and textbook, most of them just quote the final result or some results from elsewhere to calculate the one in that context.

    So I'm not having a general idea how to do this, especially this one

    [itex]\int_k^\inf \frac{z^2\sqrt{z^2-k^2}}{e^z+1}dz[/itex]

    I really appreciate any help. Thank you!
