Hi, again!
Maybe I have found something related to the Nth derivative of i[x] (I may or may not know how to get the derivative of a non-analytic function like y = 1 if x=rational otherwise -1). Really interesting. But first of all, I would like to check it myself. But I will need your help.
Here is a produktum:
\( \prod_{k=0}^{N-1} k + {{1+(-1)^k} \over 2} \)
I would like to interpolate this expression/function, but how? Any idea?
(If I will be able to get the expansion of the Taylor series of i[x], then I promise I will share it with you.)
