    Proving the Limit of an Expression: \frac{n^n}{n!}

    if you take the stirling's approximation there is no need to take log of the term on numerator. that why i asked that.

    Proving the Limit of an Expression: \frac{n^n}{n!}

    Homework Statement 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...

    Which Book Is Best for Self-Studying Mathematical Methods in Physics?

    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. I took math. methods course while i was undergrad., I passed it quite successfully. Although, I did enjoy the course, I couldn't learn much on...

    How to Derive This Four-Component Expression?

    Homework Statement I need to take the derivative of this expression explicitlyHomework Equations \partial_{\mu}Ae^{(-i/\hbar)x\bullet p}u(p)The Attempt at a Solution I tried to take the derivative of it by taking the derivatives of components of the momentum four vector "p". However, I got...

    Graduate What is the Proof of the Euler Lagrange Equation?

    Still , the function f does depend on x through y and y' . That is why I asked basically .

    Graduate What is the Proof of the Euler Lagrange Equation?

    [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...

    Why did covariant nu change sides with mu in the inhomogenous maxwell equation?

    [SOLVED] Inhomogenous maxwell equation Homework Statement In relativistic notation , the field strenght tensor can be expressed as (A is the vector potential) as on eq.(1.1) . The inhomogenous Maxwell equations can be written as on eq.(1.2) . Why did covariant "nu" changed sides with...
