Hi,(adsbygoogle = window.adsbygoogle || []).push({});

I have been working on this problem for the longest time and have just run in circles with it. Im thinking the answer is obvious but for some reason Im missing it. I need to find [tex] \int \frac{ln(x)}{x^2} dx[/tex] I know that I need to use integration by parts and have tried a number of things, however the only way that the integral seems to be simplified is if I use this set up

u=ln(x) du=1/x

v=? dv=1/(x^2)

but from here I cannot integrate 1/x^2. Am i even on the right track with this one or is there an easier way? someone please help as this problem is truly annoying me.
