    Having trouble with a particular integral

    Hey guys,

    I'm having a little trouble with the following integral:

    Integral of yln(x+y)dx

    I used integration by parts twice and came to an answer of I = (1/2)xln(x+y) but Maple got a completely different answer. I thought this was a pretty simple integral, and I was convinced that I got the correct answer, but for some reason my answer differs from a mathematical program, so I presume I'm wrong. Could someone possible have a quick check to see if they get the same answer as me?

    Thanks guys,
    Cheers

    Does y depend on x?
