Homework Help: This integral is just whooping my butt

  1. Dec 1, 2011 #1
    1. The problem statement, all variables and given/known data

    General antiderivative of:

    e^(sqrt(2x) + 3)

    2. Relevant equations

    3. The attempt at a solution


    I have no idea what to do, my process is chaotic. I arrive at an answer but it doesn't seem to agree with the book.

    Your answer looks correct, though the book answer would probably factor it: [itex](\sqrt{2x}-1)\exp(\sqrt{2x}+3)[/itex]. Is that what the difference is?

    As to your method, you could just make one substitution, [itex]y = \sqrt{2x}[/itex], rather than making two.
