As n → ∞ , it can be shown that ∞ → − ) ( ) ( x P x f n (at some points x in [ − 1, 1] ). Note: if the points of interpolation are not constrained to be equally spaced, then it is possible to choose the points of interpolation x i so that ) ( ) ( lim x f x P n n = ∞ → . However, there is no known rule that indicates how to choose appropriate points of interpolation x i to guarantee such convergence of the interpolating polynomials for arbitrary continuous functions ) ( x f ....
