Hi again,(adsbygoogle = window.adsbygoogle || []).push({});

Thaks for previous help. I am self studying GR using Schutz and Dunsby's webpages & notes.

I am stuck on a step in the derivation of the weak field approximation.

They approximate the metric with g[a][/b]=n[a]+epsilon h[a]

In step 7.30 the partial derivative h[0],[0]is taken as zero to get (7.30), -1/2 epsilon h00,i

He has neglected the time derivative!

Can you explain Why??

Thanks for any help!!!
