Web2.1 Linear Approximation In order to get a better estimate that the zero-order estimate of last section, we need to use a more complicated formula. But we want to keep the amount of complexity under control. So we want to use a simple function to approximate f(x). The simplest possible function WebA Taylor series analysis of the upwind scheme discussed above will show that it is first-order accurate in space and time. Modified wavenumber ... The spatial accuracy of the first-order upwind scheme can be improved by including 3 data points instead of just 2, which offers a more accurate finite difference stencil for the approximation of ... i am writing to ask for your advice
