Effect of dx on error

Objective: clear all close all clc x = pi/3; dx = linspace(pi/4,pi/4000,20); for i = 1:length(dx) first_order_error(i) = first_order_approx(x,dx(i)); second_order_error(i) = second_order_approx(x,dx(i)); fourth_order_error(i) = fourth_order_approx(x,dx(i)); end figure(1) loglog(dx,first_order_error) hold on loglog(dx,second_order_error,\'r\')…
