(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Using the expression below for the stress energy tensor of the em field, show that it has zero trace.

2. Relevant equations

[tex]T^{\mu\nu}=F^{\mu}_{ \alpha}F^{\alpha\nu}+\frac{1}{4}\eta^{\mu\nu}F_{\beta\gamma}F^{\beta\gamma}[/tex]

F is the faraday tensor and eta is the minkowski metric.

3. The attempt at a solution

I started by trying to calculate [tex]T^{00}[/tex] with the aim of then calculating the other diagonal components i.e. 11, 22 and 33. But I did not get anywhere. I couldnt get my head around the summations.
