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).

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,

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.
