from www.dheera.net/math/e.shtml: okay, that said... how the heck did euler decide that this x-value would equal [1/0! + 1/1! + 1/2! + 1/3! + 1/4! + 1/5! + 1/6!...(ad infinitum)]? on that page, dheera explains the usage of an "x limit." perhaps if i understood just what the heck that is, i would have an idea. help, please? i'm so close! (btw, simply using those numbers that i listed in the bracket--sans ad infinitum--, you would be able to calculate e to the third decimal. the rest of those numbers are a whole lotta nothin', i tell ya!).
