Newton in 1687. Formula (1) is called Newton's interpolation formula for unequal differences. When the $ x _ {i} $ are equidistant, that is, if $$ x _ {1} - x _ {0} = \dots = x _ {n} - x _ {n - 1 } = h, $$ 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, … See more In the mathematical field of numerical analysis, a Newton polynomial, named after its inventor Isaac Newton, is an interpolation polynomial for a given set of data points. The Newton polynomial is sometimes called … See more Newton's formula is of interest because it is the straightforward and natural differences-version of Taylor's polynomial. Taylor's polynomial tells where a function will go, based on its y value, and its derivatives (its rate of change, and the rate of change of its rate … See more Solving an interpolation problem leads to a problem in linear algebra where we have to solve a system of linear equations. Using a standard See more Given a set of k + 1 data points $${\displaystyle (x_{0},y_{0}),\ldots ,(x_{j},y_{j}),\ldots ,(x_{k},y_{k})}$$ where no two xj are the same, the Newton interpolation polynomial is a linear combination of Newton basis polynomials See more For any given finite set of data points, there is only one polynomial of least possible degree that passes through all of them. Thus, it is … See more For the special case of xi = i, there is a closely related set of polynomials, also called the Newton polynomials, that are simply the binomial coefficients for general argument. That is, … See more While the interpolation formula can be found by solving a linear system of equations, there is a loss of intuition in what the formula is showing and why Newton's interpolation formula works is not readily apparent.
