Do you want Li(x) to be the integral that starts at 0, or the integral that starts at 2? You use two different definitions in this article. Furthermore, for which values of x is Li(x) defined? AxelBoldt, Tuesday, April 2, 2002

See renewed article for improvements. I know it is not perfect. I still have to do more on a definition range of Li(x). Please be patient :-) Perhaps nice graph would solve the problem? Your futher remarks are very wellcome. And we should start to correct also Eric Weisstein's math pages because he almost does not use any definition ranges or does he? --XJam [2002.04.02] 2 Tuesday (0).
No, he often glosses over these things. Yes, a graph of li(x) would be nice. I added the ranges and corrected some formulas. I have a question about:
π(n) = ∑m=1∞ μ(m)/m ∫μn 1/ ln t dt,
where μ(m) is Möbius function.
Where did you find this formula? AxelBoldt
