Hello it has been more than three months since i don,t post now here are my questions...(adsbygoogle = window.adsbygoogle || []).push({});

a)the number [tex]i=\sqrt{-1} [/tex] is it bigger or smaller than 0?..

b)we know we can define the Bernoulli numbers as the Taylor expansion of the function [tex]\frac{x}{e^{x}-1} [/tex] my question is how would we define for example the Bernoulli number [tex]B_{1/2}[/tex] ?..

hope someone can answer....
