EFFECT OF DX ON ERROR

Objective: The code to plot the first, second & fourth order error for a range of dx is given below; MATLAB CODE: clear all close all clc % First order approximations of the first derivate against the exact solution % f(x) = sin(x)/x^3 x = pi/3 ; dx = linspace(pi/4,pi/4000,100); % Computing Analytical derivative Analytical_derivative…
