WebSo, by the chain rule, g ∘ f(x) = xtAx is differentiable and d(g ∘ f)x(h) = dgf ( x) ∘ dfx(h) = dg ( x, x) (h, h) = xtAh + htAx. This is true for any matrix A. Now if A is symmetric, this can be simplified since xtAh + htAx = xtAh + htAtx = xtAh + (Ah)tx = 2xtAh. Removing h, this … WebWhen we say that we are taking a total time derivative, we have in mind evaluating the phase space arguments of the Hamiltonian on a parameterized path ( q ( t), p ( t)) in phase space, then then taking the derivative with respect to t of the resulting expression, like this; d d t ( H ( q ( t), p ( t), t)) gulfstream metals wilmington nc
