I got that it diverged because the limit went to infinity...maybe I'll just ask about it in class and see where I went wrong, if I am wrong, which is more than likely. --[[User:Reckman|Randy Eckman]] 12:19, 5 November 2008 (UTC) | I got that it diverged because the limit went to infinity...maybe I'll just ask about it in class and see where I went wrong, if I am wrong, which is more than likely. --[[User:Reckman|Randy Eckman]] 12:19, 5 November 2008 (UTC) | ||

Okay, I'm having a bit of trouble with this one. Neither the root test nor the ratio test is pretty. Should I try to use a different test? It's kind late, so my thoughts are a bit scrambled. I think I'm gonna try to rewrite the sum and see what that gets me.
$ \frac{n!}{n^n}=\frac{(n-1)!}{n^{n-1}} $
Don't know what that will do, but we'll see. His Awesomeness, Josh Hunsberger
Nevermind, I figured it out. You just have to do a second comparison between the resultant denominator in the limit with a simpler version, and show how that the limit is less than one. If you have difficulty, just give me a shout
