Question

C++/Computational Physics: Write a program that implements the forward difference routine to calculate a derivative. Use it to evaulate the derivative of the following function at x=0.8

f(x)=sin(cos(x^2))

Answer 1

CODE:

Below is the code to your question

clc

clear all

close all

h=-10;

h=10.^h;

x=0.8;

f=@(x) sin(cos(x.^2));

Dy=(f(x+h)-f(x))/h;

fprintf('The derivative using forward difference at x=0.8 is %.4f\n',Dy)

THANK YOU.
