it's rather a bypass question, not a direct question about 'e'. the last term in the binomial expansion of (1+1/n)^n is according to my text: (1/n!)(1-1/n)(1-2/n)....(1-(n-1)/n) while it should be (1/n!)(n(n-1)...1)/n^n okay, these two terms are almost identical, the first equals (with disregarding of 1/n!): ((n-1)(n-2)...1)/n^n and second one is the first multiplied by n, then what is the problem. i assume it's with me ( just kidding).
