WebDue to the properties of the determinant, in order to evaluate the corresponding variation of det, you only have to be able to compute determinants of things like I + ϵ. It can be shown that det (I + ϵ) = 1 + trϵ + O(ϵ2), and I think that's the reason. Or a reason.. – Peter Kravchuk May 24, 2013 at 19:59 2
