Lost on an Integral

  1. Oct 4, 2007 #1
    I have an integral I want to work out that should be a simple one but I just can't see where to start with it. Any help would be appreciated.

    [tex]

    \int\frac{lnx}{x-8xln^2x}

    [/tex]

    Write it as:
    [tex]\frac{1}{2}\int\frac{2\ln(x)}{x}\frac{dx}{1-8\ln^{2}(x)}[/tex]

    Substituting for ln^2(x) works even better..:smile:
