## Homework Statement

Calculate the invariant

[tex]

E^{\alpha \beta} E_{\alpha \beta}

[/tex]

## Homework Equations

## The Attempt at a Solution

we apply the metric in this case,

[tex]

E^{\alpha \beta} E_{\alpha \beta} = g_{\alpha n} g_{\beta m} E_{n m} E^{n m}

[/tex]

is that even correct?
