Generalizing to arbitrary. Eduardo Silva 4 4 silver badges 9 9 bronze badges. Whittaker, E. Note that the function passes through the pointsas can be seen for the case. Uniqueness can also be seen from the invertibility of the Vandermonde matrix, due to the non-vanishing of the Vandermonde determinant. Uses of Lagrange polynomials include the Newton—Cotes method of numerical integration and Shamir's secret sharing scheme in cryptography. Lucas de Gelder 3 3 3 bronze badges. I have the following question: And the following Lagrange interpolation error bound: The way I have started to solve the problem is as follow.
The Lagrange interpolating polynomial is the polynomial P(x) of degree. §17 in The Calculus of Observations: A Treatise on Numerical Mathematics, 4th ed.

Example No 1: Interpolate the value of the function Solution: Using Lagrange's formula of interpolation, we have.
Lagrange interpolationwhich is one of the simplest and mostly employed interpolation methods, consists of finding the interpolation coefficients as the solution of the linear system. Lagrange interpolation is susceptible to Runge's phenomenon of large oscillation.
Can anybody explain to me what Lagrange Interpolating Polynomial is with examples? Although named after Joseph Louis Lagrangewho published it inthe method was first discovered in by Edward Waring  It is also an easy consequence of a formula published in by Leonhard Euler.
The determinant of such a system is a Vandermonde determinant which is always non-vanishing and therefore the system always admits a unique solution, provided that the interpolation points are all different.
