I'm doing a selfstudy on relativistic electrodynamics and stumbled over a problem (which i find rather important) i can't solve. It's concerning problem 12.55 in Griffiths introduction to electrodynamics.
One needs show that the four gradient:
\frac{\partial}{\partial x ^\mu} functions as a covariant fourvector, using a scalar function (call it \phi) and the chain rule.
Any help would be much appreciated!
