“…Cheng [4,5] and Guo [6] estimated the rates of convergence of Bernstein operators B n ( f, x), Sza sz operators S n ( f, x) and Durrmeyer operators D n ( f, x) for functions of bounded variation and proved that the operators B n ( f, x), S n ( f, x) and D n ( f, x) all convergence to the limit 1 2 f (x+ )+ 1 2 f (x& ) for functions of bounded variation. References [2,3] proved that the operators B n, : ( f, x), L n, : ( f, x) and S n, : ( f, x) all convergence to the limit (1Â2 : ) f (x+ )+(1&1Â2 : ) f (x& ) for functions of bounded variation (: 1, n Ä + ).…”

“…For example, Bojanic and Vuilleumier [1] estimated the rate of convergence of Fourier Legendre series of functions of bounded variation on the interval [0, 1], Cheng F. [3] estimated the rate of convergence of Bernstein polynomials of functions of bounded variation on the interval [0, 1], Zeng and Chen [16] estimated the rate of convergence of Durrmeyer type operators for functions of bounded variation on the interval [0,1]. On the other hand, in recent years, there is an increasing interest in modifying linear operators so that the new versions reproduce some basic functions, e.g.…”
