Newton's Interpolation Formulae As stated earlier, interpolation is the process of approximating a given function, whose values are known at tabular points, by a suitable polynomial, of degree which takes the values at for Note that if the given data has errors, it will also be reflected in the polynomial so obtained.

12.01.2022 · Newton's forward difference formula is a finite difference identity giving an interpolated value between tabulated points in terms of the first value and the powers of the forward difference . For , the formula states (1) When written in the form (2)

These interpolation formulae are applicable for interpretation near the beginning and end of tabulated values. However, the gaussian forward formula are best suited for interpolation near the middle of the table. The coefficients in the central difference formula such as that of gauss are smaller and converge faster than those in Newton's formulae.
