Is this integration probelm right so far?

    [tex]\int_{e}^{infinity} \frac{dx}{x \ln x} = \int_{e}^{infinity} \frac{1}{x \ln x} dx = \int_{e}^{infinity} \frac{1}{\ln x} d \ln x = ln|lnx| + C [/tex]evaluated from e to infinity

    I think I know what I need to do next, I just want to make sure I'm good up to this point. Also, how do you put in an infinity sign, and evaluate sign? Thanks!

    Infinity is just \infty. Dunno about the other.

    Anyway, it looks correct to me.

    Looks right. (And divergent:smile:)
