## This is not A Homework problem, I am just wondering.

What would the integral of ln|x| be.

 Applying integration by parts which states $$\int u\frac{dv}{dx}\,dx = uv - \int v \frac{du}{dx}\,dx$$ $$u=ln(x)$$ and $$v=x$$ So $$\int ln(x)\,dx = xln(x) - \int x\frac{1}{x}\,dx = xln(x)-x+c$$
 I wouldn't have thought to use parts. Thanks, I appreciate it
