Abstract

In this paper, we construct a variant of the Kantorovich Szazs type operators involving the Tangent polynomials and estimate convergence properties of these operators by using Korovkin theorem. Also we obtain the rate of convergence by using modulus of convergence and Peteer’s K-functional.

Abstract

Bu çalışmada, Tanjant polinomlarını içeren Kantorovich-Szász tipli operatörlerin bir varyantı oluşturulup, Korovkin teoremi kullanılarak bu operatörün yakınsaklık özellikleri tahmin edilmiştir. Ayrıca Peetre’s K- fonksiyoneli ve süreklilik modülü kullanılarak yakınsaklık hızı elde edilmiştir.
