Newton's Backward Difference Interpolation Formula. arrow_back Numerical Methods. For interpolating the value of the function y = f (x) near the end of table of values, and to extrapolate value of the function a short distance forward from y …

This formula is known as Newton’s backward interpolation formula. This formula is also known as Newton’s-Gregory backward difference interpolation formula. If we retain (r 1)terms, we obtain a polynomial of degree r agreeing with f (x) at x n ,x n-1, …, x n-r. Alternatively, this formula can also be written as. Here.

NEWTON'S BACKWARD DIFFERENCE FORMULA This is another way of approximating a function with an n th degree polynomial passing through (n+1) equally spaced points. As a particular case, lets again consider the linear approximation to f(x)

EXPERIMENT NUMBER 11. IMPLEMENTATION OF NEWTON BACKWARD DIFFERENCE INTERPOLATION METHOD. INTRODUCTION We use Newton Interpolation which is based on developing difference tables for a given set of data points. Newton's backward difference formula is a finite difference identity giving an interpolated value between tabulated points f(p) …

Oct 17, 2017 · Thus, the first backward differences are : NEWTON’S GREGORY BACKWARD INTERPOLATION FORMULA: This formula is useful when the value of f(x) is required near the end of the table. h is called the interval of difference and u = ( x – an ) / h, Here an is last term. Example: Input : Population in 1925. Output : Value in 1925 is 96.8368. Below is the implementation of the Newton backward interpolation method.

This polynomial is called the Newton - Gregory backward difference formula. The error in this interpolation. En(x) =. s (s + 1) . . . (s + n) hn+1f(n+1)( x) ( x0 < ( x ) < xn ) (n + 1)! Example : Find f (0.15) using Newton backward difference table from the data.

$\begingroup$ You can do it yourself. Take a problem for forward interpolation from your text book and solve it by backward interpolation. Take another problem for backward interpolation and solve it by forward interpolation.

29.10.2021 · Newton Backward Difference Polynomial: As explained for Newton’s forward difference polynomials, we can also use backward difference formulas to develop polynomials. We can use backward differences . For a uniformly spaced data, if x n is the base in an (n+1) data (x 0,f 0),(x 1,f 1),..,(x n,f n)

The formula is called Newton's (Newton-Gregory) forward interpolation formula. So if we know the forward difference values of f at x 0 until order n then the above formula is very easy to use to find the function values of f at any non-tabulated value of x in the internal [a,b].The higher order forward differences can be obtained by making use of forward difference table.
