Talk:Logarithmic Integral as Non-Convergent Series

What the heck is $\ln 0$? --GFauxPas (talk) 23:25, 17 June 2013 (UTC)

Formally it should be $\lim_{x \to 0} \dfrac x {\log x} = 0$. Since $1/\log(t)$ isn't defined at 0, li$(z)$ is defined by:
 * $\displaystyle\lim_{\epsilon \to 0} \int_\epsilon^z \frac {dt} t$
