Phil Dias Taylor Comparison of 4th order approximations of the second order derivative

Objective: Octave code: % Taylor table method for higher order approximations using skewed and symmetric stencils clear all close all clc % Analytical function = exp(x)*cos(x) x = pi/3 ; analytical_derivative = -2*exp(x)*sin(x); dx = linspace(pi/4,pi/4000, 10); % Skewed RHS A = [1 1 1 1 1; 0 1 2 3 4; 0 1/2 2 9/2 8; 0 1/6 4/3 9/2…
