Homework Help: What kind of Integration to use

  1. Jun 18, 2014 #1
    1. The problem statement, all variables and given/known data
    ∫(x2)/(ex/2) dx

    2. Relevant equations

    3. The attempt at a solution
    I'm not completely sure where to start on this one. I don't see any sort of u substitution working, would integration by parts be a good idea? Maybe let u=x2 and dv=(1/ex/2) ?

    Don't ask: just go ahead and try it for yourself!

    BTW: you should always write ##1/e^{ax}## as ##e^{-ax}## whenever ##a > 0##.

    Haha ok, thanks! It doesn't look as scary now with that e rewritten :)
