Abstract
In this paper we introduce a new class of linear approximating operators \left( L_{nr}\right) _{n\geq1},r=0,1,2,…, for the functions f\in C^{r}\left[ 0,1\right]. In order to construct them we use Taylor’s polynom of r degree and a classical class of linear positive operators generated by a probabilistic method. Also, we study approximation degree with the modulus of continuity of first and second order. \left( L_{nr}\right) _{n\geq1} include as a particular case the generalized Bernstein polynomials defined by G.H. Kirov in [5].
