Homework Statement
Is the sequence {(n!)/(n^n)} convergent or divergent. If it is convergent, find its limit.
Homework Equations
Usually with sequences, you just take the limit and if the limit isn't infinity, it converges... That doesn't really work here. I know I'm supposed to write out the terms, but I can't figure out where to go from there.
The Attempt at a Solution
(n!)/(n^n) = ((1)(2)(3)...(n-1)(n))/((n)(n)(n)...(n)(n))
I think I'm supposed to say that this is less than something that goes to zero, but I don't know what that something should be.
n/n = 1
Does this mean that I can cancel that out and have a list of numbers smaller than n divided by n? Then the sequence is less than 1...but I think it converges to zero, I just don't know how to show that.
