In our algorithms class, my professor insists that n! Has a higher order of growth than n^n. 法二(错位相减): 考虑幂级数 ∑ n = 1 ∞ n x n (1 x) ∑ n = 1 ∞ n x n = ∑ n = 1 ∞ n x n ∑ n = 1 ∞ n x n + 1 = x + ∑ n = 1 ∞ (n + 1) x n + 1 ∑ n = 1 ∞ n x n + 1 = x + ∑ n = 1 ∞ x n +.
You'll need to complete a few actions and gain 15 reputation points before being able to upvote. This doesn't make sense to me, when i work through what each expression means. I'm trying to find $$\\lim_{n\\to\\infty}\\frac{n}{\\sqrt[n]{n!}}.$$ i tried couple of methods:
