    Help needed with derived integral

    Hi

    I reeeaallly need some help here. This equation

    ImageShack® - Online Photo and Video Hosting

    (listed in numerous journals) is related to the calculation of the capacity factor of a wind turbine from certain parameters. I have them all (weibull k & c values, turbine characteristics etc), so should be able to do it. However, there are some gamma functions that i have absolutely no idea what to do with. As you can tell - calculus is not my strong point.

    Could someone help with this? It'd be hugely appreciated.

    The gamma function is defined for all complex numbers (except non-positive integers) by the definite integral,

    \Gamma(z) = \int_0^\infty  t^{z-1} e^{-t}dt

    The lower incomplete gamma function is defined by,

     \gamma(s,x) = \int_0^x t^{s-1}\,e^{-t}dt

    For information about these refer, Gamma function - Wikipedia, the free encyclopedia and Incomplete gamma function - Wikipedia, the free encyclopedia.

    Hope this will help you.
