| Apr 6, 2023 at 13:21 | comment | added | Peter Mueller | @PietroMajer In kconrad.math.uconn.edu/blurbs/analysis/gaussianintegral.pdf Keith Conrad records 11 methods to compute the Gaussian integral, none uses this idea with the lattice point count combined with the discretization of the integral by a Riemann sum. So maybe it is worth a short note in the Amer. Math. Monthly? | |
| Apr 6, 2023 at 7:53 | comment | added | Pietro Majer | It seems a discrete version of the Poisson's computation of the Gaussian integral from $\int_{\mathbb R^2}e^{-(x^2+y^2)}dxdy$ (via double integration vs integration in polar coordinates) | |
| Apr 5, 2023 at 19:25 | comment | added | Pietro Majer | It’s also a cool way of evaluating $\int_0^\infty e^{-x^2}dx$, if one put it together with the other solutions | |
