Math Problem Statement

Newton's Backward interpolation formula can be used (A) only for equally spaced intervals (B) only for unequally spaced intervals (C) for both equally and unequally spaced intervals (D) for unequally intervals.

Solution

In your question about Newton's backward interpolation formula, the correct option to select is:

(A) only for equally spaced intervals

Newton's backward interpolation formula is specifically designed for equally spaced data points. This method uses backward differences of the data, which are computed at equal intervals, to estimate the value of a function at a point. It is important for the intervals to be equal so that the differences calculated represent consistent steps backward from the point of interest, which ensures the accuracy and reliability of the interpolation.

Would you like more details on how Newton's backward interpolation formula works, or have any other questions?

Here are some further inquiries you might find interesting:

  1. What are the primary differences between Newton's forward and backward interpolation formulas?
  2. How do you calculate backward differences?
  3. Why is it important for the intervals to be equally spaced in Newton's backward interpolation?
  4. Can you provide an example where Newton's backward interpolation formula is used?
  5. What are other interpolation methods that can handle unequally spaced intervals?

Tip: Understanding the context and application of different interpolation methods can greatly help in choosing the most suitable method for specific data sets.
