1. Homework Statement
I need to take the derivative of this expression explicitly


2. Homework Equations
[tex]\partial_{\mu}Ae^{(-i/\hbar)x\bullet p}u(p)[/tex]


3. 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 stuck while trying to recombine the expression left from derivation.

=Ae^{(-i/\hbar)x\bullet p}u(p)[-i\hbar\partial_{\mu}(x^{\nu}p_{\nu})][/tex],
which should be easy.
