Actually $e^{\frac{x^2}{2}}$ must also converge as we have $\frac{x^2}{2}, and indeed it also converges! But it seems that this already the limit, i.e. every series $e^{c x^2}$ for $c>\frac{1}{2}$ does not converge. I guess that this is the same for $e^{\frac{x^n}{n!}$, $n>1$, while Faulhaber always works for $n=1$, i.e. $e^{c x}$. Do you have any idea how to sum $e^{x^2}$? « Next Oldest | Next Newest »
