Note on approximation properties of generalized Durrmeyer operators

Purpose: To study the rate of convergence of q analogue of Durrmeyer operator generalization proposed by N. Deo.Methods: We first estimatemoments of q-Durrmeyer operators. We also study the rate of convergence our operators.Results: We use Maple programming to draw the graphs for the approximation process for two operators. In all graphs, we observe that either classical operator has sharp convergence or both operators behave alike after a large number of iterations.Conclusions: We conclude that the modified operator does not improve the approximation process.
