I think I have an idea how to sum \( e^{x^2} \).
Recall that \( e^{x^2} = \lim_{n \to \infty} \left( 1 + \frac{x^2}{n} \right)^n \)
Now calculate the polynomial sum of \( \left( 1 + \frac{x^2}{n} \right)^n \) (using Faulhaber's formula).
This seems to convergent to a nice function.
Wow, what a debut! Hey Kobi, welcome to the forum!
Did you also find out something about the uniqueness of the obtained functions?
Are there perhaps examples where you group the terms in a different way and get different results?
