This polynomial is known as the Hermite-Fejér interpolation polynomial. It is of particular notice that the above Hermite-Fejér interpolation polynomial converges much slower compared with the corresponding Lagrange interpolation polynomial at the Chebyshev pointsystem (3)(see Fig. 1). To get fast convergence, the following Hermite-Fejér interpolation of f (x) at nodes (1) is considered [6, 7]:
