Which of the following formula is used to fit a polynomial for interpolation with equally spaced data?
Show Hint
For equally spaced data, Newton's forward interpolation is used, while for unequally spaced data, use Lagrange's or Newton's divided difference formul(A)
Updated On: Feb 27, 2025
- Newton's divided difference interpolation formula
- Lagrange's interpolation formula
- Newton's forward interpolation formula
- Least-square formula
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Understanding interpolation methods.
- Newton's forward interpolation formula is specifically used for equally spaced dat(A)
- Newton's divided difference and Lagrange's interpolation work for unequally spaced dat(A)
Step 2: Selecting the correct option.
Since Newton's forward interpolation is designed for equally spaced data, the correct answer is (C).
