Abstract

Abstract The goal of this paper is to construct a new type of Bernstein operators depending on the shape parameter λ ∈ [–1,1]. For these new type operators a uniform convergence result is presented. Furthermore, order of approximation in the sense of local approximation is investigated and Voronovskaja type theorem is proved. Lastly, some graphical results are given to show the rate of convergence of constructed operators to a given function f.
