Homework Statement
I am lost as to what to do here.
Homework Equations
Integral of (lnx)/(4x)
The Attempt at a Solution
let u = lnx
let du = (1/x)dx
(u)/(4x) dx...
But then howdo you make 4x disappear in the equation? Typically I did it by making du = something in the equation I want to take out, but how can you make 1/x = 4x?
