Discretization Basics

Objective: Code is as follows clear all close all clc x = pi /3; % given value of x dx = pi/25 %grid spacing %given function f(x) =sin(x)/x^3 = sin_x is saved as function in another %file analytical_derivative = (x^3*cos(x)-sin(x)*3*x^2)/x^6; %First order approximation using forward differencing scheme % forward_differincing…
