Homework Help: Integral of Exponential function

  1. Mar 5, 2009 #1
    1. The problem statement, all variables and given/known data

    1. [tex]\int^{\infty}_{-\infty}e^{-ax^2 - bx^{\frac{5}{2}}}dx[/tex]

    2. [tex]\int^{\infty}_{-\infty}x^ne^{-ax^2 - bx^{\frac{5}{2}}}dx[/tex]

    (n is integer)

    2. Relevant equations

    Does anyone can give me the integral in the closed form or introduce any useful references?

    Thank you.

    Hi macauor, Welcome to PF!

    What is putting you off? Can you show us any workings out?

    Hello, The Bob
    Thank you for your warm welcome!
    I want to obtain the closed forms of the integration of the above two integrals.
    Do you have any suggestion about that?
