KW - Rational function approximation, Newman-type rational approximation, interpolation nodes, convergence rate.
AB - <p style="text-align: justify;">In the present note, we consider the problem: how many interpolation nodes
can be deleted from the Newman-type rational function such that the convergence rate
still achieves.</p>
