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: http://www.phys.ufl.edu/~coldwell/interpolation/SplineFitting/Spline%20vs%20Lagrange.htm fittuber sunscreen

"The Lagrange form of the interpolation polynomial shows the linear character of polynomial interpolation and the uniqueness of the interpolation polynomial. Therefore, it is preferred in proofs and theoretical arguments. Uniqueness can also be seen from the invertibility of the Vandermonde matrix, due to the non-vanishing of the Vandermonde determinant.
