    Re: Integral: x/1+sqrt(x)

    Do the substitutions that neutrino and morphism suggested.

    Can't you use integration by parts?

    Re: integral

    I'm doing this in my head and not fully awake, so I could be wrong.
    we have 1/(1+sqrt(x)) You can use the substitution that you've shown.
    So we end up with 2u/1+u
    remember you can substitute more than once....
