As with other difference formulas, the degree of a Newton interpolating polynomial can be increased by adding more terms and points without discarding existing ones. Newton's form has the simplicity that the new points are always added at one end: Newton's forward formula can add new points to the right, and Newton's backward formula can add new points to the left. The accuracy of polynomial interpolation depends on how close the interpolated point is to the …

Newton’s Polynomial Interpolation¶. Newton’s polynomial interpolation is another popular way to fit exactly for a set of data points. The general form of the an \(n-1\) order Newton’s polynomial that goes through \(n\) points is:

Due to the uniqueness of the polynomial interpolation, this Newton interpolation polynomial is the same as that of the Lagrange and the power function interpolations: . They are the same nth degree polynomial but expressed in terms of different basis polynomials weighted by different coefficients.

In the method of interpolation, it is assumed that the function is capable of being expressed as a polynomial. This assumption is based on Weierstrass approximation theorem. That is, the existence of an interpolating polynomial is supported by the theorem. P. Sam Johnson (NITK) Newton’s Interpolation Methods February 7, 2020 7/47
