Derivative of determinant wrt matrix
WebMay 27, 2015 · So, a derivative of a sum is the same as a sum of derivatives. Hence, you simply differentiate the function (i.e. density) under the integral, and integrate. This was my bastardized version of the fundamental theorem of calculus, that some didn't like here. Here's how you'd do it with the normal probability. WebNov 15, 2015 · In terms of the variation of the metric tensor this means you can quickly find that δ g = g ( g μ ν δ g μ ν), which lets you compute δ − g = − 1 2 − g δ g = 1 2 − g − g ( g μ ν δ g μ ν) = − 1 2 − g ( g μ ν δ g μ ν) Share Cite Improve this answer Follow edited Nov 15, 2015 at 17:56 answered Nov 15, 2015 at 17:51 antibrane 126 4 Thank you!
