The derivative of the determinant of a matrix - The DO Loop

WebIn the case of the metric, this implies that − det ( g + δ g) ≈ − det ( g) [ 1 + g a b δ g a b] and so δ ( − g) = ( − g) g a b δ g a b. To complete the calculation you'll then have to relate δ g a b to δ g a b, but this should get you on your way. If this isn't a homework problem or the like, let me know and I can expand on this latter part.
