This is my first time seeing the product function in action. I knew what it was, but I haven't necessarily used it much. You made it very easy to understand. So thank you for that. :)

I think Euler used the sinc function (sin(x)/x) to reason about the constant multiple in each root in the infinite product (i.e. (1-(x/kpi)^2) vs (x^2 - (kpi)^2) vs all other constant multiples) which sort of justified why each term in the product looks the way it does.

Euler 'used' the "sinc-function" 'quite often' , e.g. : cos (na) + i * sin (na) = [ cos(a) + i*sin(a) ]^n --> set here a = x/n , with a fixed & real x --> cos(x) + i*sin(x) = [cos(x/n) + i*sin(x/n]^n --->> sin(x/n) / (x/n) --> 1 , for x/n --> 0 , i.e. for n --> inf --->> so asymtotically 'we' have sin(x/n) ~ x/n , moreover 'we' see / "know" that cos(x/n) ~ 1= cos(0) , for large n --->>> ; so it's "plausible" to write : cos(x) + i*sin(x) = lim [ 1 + ix/n]^n , for n --> inf , thus 'we' get a 'definition' for the exponential function [ on which the "Euler method" for solving ODE's numerically is based ! ] : e^x = lim [ 1 + x/n ]^n , n --> inf , according to the last "well known" limit ... !!! { exercise : show that lim [ 1 + x/n ]^n = sum(k = 0 to inf) x^k/k! , n --> inf }

Hey this was posted on my birthday! Love this proof :)

My calc teacher showed my class this back in the day. Still cool to this day.

What's nice is that the same approach for the zeros of the cosine function can be used to get that the sum of 1/(2k+1)² from 0 to infinity is Pi²/8. Then it's easy to realize that the even squares are 1/4 of the sum of 1/k². From that it follows that sum of 1/k² is (4/3) of Pi²/8= Pi²/6.

It came up when I was trying to integrate Planck's Law, and did not just want to simply write down the value of zeta(4) written in the book. So... now that when people ask me to calculate the value of zeta(2) or zeta(4), I just claim that I know the other one, and use the method in the article.
