| Abstract: | We point out that the Meyer-Konig and Zeller operator M. (f;x) are unbounded in usual Jacobiweighted norm at first, and then we consider the weighted approximation by M.(f ;x) by a new norm andobtain the characterization of convergence rate in nonoptimal approximation by K-functional. |
