Taylor table method and Matlab code for Fourth order approx of second derivative

Objective: MATLAB CODE % Taylor table method % 4th order approx of second order derivative clear all close all clc %analytical function ==> exp(x)*cos(x) %analytical derivative ==> -2*exp(x)*sin(x) x=pi/3; ad = -2*exp(x)*sin(x); %numerical derivative(nd) dx = pi/20; %central diff method(nd1) - (af(i)+bf(i-1)+cf(i+1)+df(i-2)+ef(i+2))/(dx^2)…
