Objective: clear all clc close all %analyical derivative of function sin(x)/x^3 %at x=pi/3 x=pi/3; analytical_derivative=(x^3*(cos(x))-3*x^2*(sin(x)))/x^6; %numerical_derivative by forward difference method dx=pi/400000; forward_differencing=((sin(x+dx)/(x+dx)^3)-(sin(x)/x^3))/dx; %error error1=abs(forward_differencing-analytical_derivative);…
