I integrated the function to become

ln x / (x^2)

u = lnx

du = 1/x

dv = 1/x^2

v = -1/x

UV - int VDU

lnx * -1/x - - int of 1/x^2 becomes -1/x

so

- lnx/x - lnx (or close to this)

So where the hell does this mystical one come from? It looks as if it'd be divergant from this!!! Please help!!!!!!!
