Web6 Dec 2014 · We only need the first N + 1 terms of the expanded sum from the binomial theorem; 1 k! ≤ (n + N k) ⋅ 1 nk. Now keep N fixed and let n → ∞; this shows that SN ≤ e. Finally, since this is true for EVERY N, we get the opposite inequality: the sum of the series of inverses of factorials is ≤ e. WebThe alternating factorial is defined as the sum of consecutive factorials with alternating signs, (1) They can be given in closed form as. (2) where is the exponential integral, is the E n -function , and is the gamma function . The alternating factorial will is implemented in the Wolfram Language as AlternatingFactorial [ n ].

The factorial of a number is the sum of the multiplication, of all the whole numbers, from our specified number down to 1. For example, the factorial of 6 would be 6 x 5 x 4 x 3 x 2 x 1 = 720. cochise long way
