comment How do I calculate the perturbations to the metric determinant?
great! thanks for that. Since I already worked it out ted's way, i'll compare it to your way to make sure I got the right answer.

I think one of your g^(-1) 's should just be g, but everything else looks good. Very helpful!

comment How do I calculate the perturbations to the metric determinant?
Thanks, I think that helps. I can check my answer against a specific metric once I'm done to see if I messed up (hopefully). I think the only thing missing is how to interpret g^(-1)*h raised to some power, but I can use trial and error I guess. Thanks alot for your help!

wait... how to I calculate the power series of ln(g+h) (expanded in powers of h) for g and h both matrices?

that might be just what I need. I'll see if it works.
