CST8233: Lab #11
Numerical differentiation
Objective
The objective of this lab is to familiarize the student with the theory topics covered in
Week 10. Mainly, this lab focuses on Numerical differentiation
Earning
To earn your mark for this lab, each student should finish the lab’s requirements share his run
screen within our zoom meeting.
Discussion
Write a c/c++ Program to compute the first derivative of the function f(x)= x3
using forward, Backward and centered derivative numerical method
To test your program:
Enter the total no. of equally spaced data points:
3
Enter the value of x's :
2
3
4
Enter the point where first derivative is calculated
3
the value of y's :
8
27
64
The result is
Forward method= 37 error = 37.04%
Backward method=19 error= 29.93%
Central = 27 error= 3.704%
