WebIn other words, the interpolation polynomial is at most a factor Λn(T ) + 1worse than the best possible approximation. This suggests that we look for a set of interpolation nodes with a small Lebesgue constant. The Lebesgue constant can be expressed in terms of the Lagrange basispolynomials: WebCubic Splines []f (x) 2 a b dx []S (x) 2 a b dx 0 We have proven that a cubic spline has a smaller or equal curvature than any function which fulfills the interpolation requirements. This also includes the function we started with. Physical interpretation: a clamped flexible rod picks the minimum curvature to minimize energy - spline
