How to integrate *THIS* ?

  1. Apr 9, 2009 #1
    [tex]\int e^\sqrt[3]{x}[/tex] dx

    Integration by parts, perhaps? But if that's the case, I have no idea which is right value for u and which is the right one for dv... Taking ln on both sides? Uh...hmm...I don't think that's how you work this question out...

    Any ideas, guys? :|

    I'm quite certain that integral in not expressible in terms of elementary functions.

    Yeah it can... Let u^3=x

    OH YES. First I did that, then I used integration by parts twice to eliminate the u^2 all the way to du, then ta-daa!
