Hi. I am reading a physics text, and in one of the lines it uses the following relation:(adsbygoogle = window.adsbygoogle || []).push({});

[tex]

\mathrm{det}(\delta^\mu_\lambda +\frac{\partial \delta x^\mu}{\partial x^\lambda}) = 1 + \mathrm{Tr}\frac{\partial \delta x^\mu}{\partial x^\lambda}

[/tex]

where [itex]\mu [/itex] and [itex]\lambda [/itex] are matrix elements, and [itex]\delta^\mu_\lambda [/itex] is Kronecker's delta. I am trying to derive this, but I am not sure how. Help will be appreciated
