Considered at a fixed interval on a function approximation using interpolation. Clearly, Lagrange interpolation nodes are used the more the number of interpolation polynomial higher. We are naturally concerned about the increasing interpolation polynomials, Ln (x) is also closer to being a function approximation. Runge (Runge) give an example of a well-known and are very stimulating.
