Homework Help: Intergration of imcomplete gamma distribution

  1. Jun 24, 2009 #1
    1. The problem statement, all variables and given/known data

    How can i determine the integration of incomplete gamma function. I mean how to determine int_0^1 gammainc(3/4,r). where gammainc(a,x)=int_0^x t^(a-1)e^(-t) dt

    2. Relevant equations

    3. The attempt at a solution

    Do you mean numerical integration or what?
    For properties of the incomplete gamma function see http://en.wikipedia.org/wiki/Incomplete_gamma_function" [Broken]
