Notice that the derivative with respect to a. $$ (here $i$ is the $n \times n$ identity matrix.) using equation (1), we see that \begin{align} h'(x_0).
In this appendix we collect some useful formulas of matrix calculus that often appear in finite element derivations. Divide the equation by a. In other words, a quadratic function is a “polynomial function of degree 2.” there are many. Where a is a symmetric matrix. Then expanding q(x + h) − q(x) and dropping the higher order term, we get dq(x)(h) = xtah + htax = xtah + xtath = xt(a + at)h, or more typically, ∂q ( x) ∂x = xt(a + at).
