what is the limit of this expression?
lim_{n\rightarrow\infty}\frac{n^n}{n!}
Homework Equations
The Attempt at a Solution
I tried to make it look like \frac{x^n}{n!} and also tried to apply the sandwich theorem, but got nothing logical.
Probably the limit is \infty, still...
Lately a book for mathematical methods in physics is discussed on many topics. However, I couldn't find a sufficient answer for my specific problem.

[SOLVED] Euler Lagrange Equation
Hi there ,
I am missing a crucial point on the proof of Euler Lagrange equation , here is my question :
\frac{\partial f}{\partial y}-\frac{d}{dx}\left(\frac{df}{dy^{'}}\right)=0 (Euler-Lagrange equation)
If the function "f" doesn't depend on x explicitly...
