The function itself occurs when m = 0. A bivariate function y = F(x 1;x 2) can be di erentiated m 1 0 times with respect to x 1 and m 2 0 time with respect to x 2. The order of the derivative is m 1 + m 2 and the derivative is represented by F(m 1;m 2)(x 1;x 2). The ...

WebOrder of Accuracy 1 Terminology We consider a numerical approximation of an exact value u. The approximation depends on a small parameter h, which can be for instance the grid size or time step in a numerical method. We denote the approximation by u˜h. The numerical method has order of accuracy p if there is a number C independent of h such that Web15 May 2013 · ARY NEWS. @ARYNEWSOFFICIAL.
