Theorem 4.1 Uniqueness of interpolating polynomial. Given a set of points x 0 < x 1 < ··· < x n, there exists only one polynomial that interpolates a function at those points. Proof Let P(x) and Q(x) be two interpolating polynomials of degree at most n, for the same set of points x 0 < x 1 < ··· < x n. Also, let R(x) = P(x)−Q(x).

Newton’s interpolation polynomial of degree n n, P n(x) P n ( x), evaluated at x0 x 0, gives: P n(x0) = n ∑ k=0αkek(x0) = α0 = f (x0) = f [x0] P n ( x 0) = ∑ k = 0 n α k e k ( x 0) = α 0 = f ( x 0) = f [ x 0] Generally speaking, we write: f [xi] = f (xi), ∀i = 0,…,n f [ x i] = f …

with $ P(X) $ the Lagrange polynomial and the dots $ (x_0, y_0),\dots,(x_n, y_n) $ and $ x_i $ distinct. From the points whose coordinates are known, the lagrange polynomial calculator can thus predict other points based on the assumption that the curve formed by these points is derived from a polynomial equation.

Lagrange interpolating polynomials are implemented in the Wolfram Language as InterpolatingPolynomial[data, var]. They are used, for example, in the construction of Newton-Cotes formulas. When constructing interpolating polynomials, there is a tradeoff between having a better fit and having a smooth well-behaved fitting function.

Suppose we interpolate through n + 1 data points with an at-most n degree polynomial p(x) (we need at least n + 1 datapoints or else the polynomial cannot be fully solved for). Suppose also another polynomial exists also of degree at most n that also interpolates the n + 1 points; call it q(x). Consider . We know,
