Approximation by StancuChlodowsky polynomials
In this paper, we investigate convergence and approximation properties of a Chlodowsky type generalization of Stancu polynomials (we called StancuChlodowsky polynomials).The rates of convergence of this generalization are obtained by means of modulus of continuity and by using the K K -functional of Peetre. We also present and prove theorems on weighted approximation and the order of approximation of continuous functions by these operators on all positive semi-axis.
