 Apr 2 awarded Commentator Apr 2 comment Does this sequence of polynomials converge to the square root function? @TrialAndError I am just interested in this method. In particular, I feel that there should be a relatively straightforward inductive proof for this problem, but I can't seem to do it. Apr 1 comment Does this sequence of polynomials converge to the square root function? @Crostul Nope, it's actually an exercise (problem 7 in $\text{III, §4}$).

As for when it is true, I believe it is true for any finite abelian group.

Damn, you're right. I've been jumping between books as of late and it was only a matter of time before I forgot about some of his notation. And yes, it's been an amazing book so far. Every other page reminds me of those "one weird trick" scams except I am left satisfied. Nov 4 accepted Stirling numbers of the second kind — a series-expansion typo?
