Abstract :The paper is a survey concerning representations for the remainder term of Bernstein-Schurer-Stancu and respectively Stancu insert ignore into journalissuearticles values(based on factorial powers); bivariate approximation formulas, using bivariate divided differences. As particular cases the remainder terms of bivariate Bernstein-Stancu, Schurer and classical Bernstein bivariate approximation formulas are obtained. Finally, one presents some mean value properties, similar to those of the remainder term of classical Bernstein univariate approximation formula.
Keywords : Bernstein Schurer Stancu bivariate operator, Stancu bivariate operator, Bivariate divided difference, Bivariate approximation formula, Remainder term
