| Abstract: | By means of the Steklov mean functions function, the derivatives of generalized Baskakov and the first order, second order modulus of continuity of operators are estimated, and the equivalent conditions of the estimation of derivatives of generalized Baskakov operators are obtained. Thereby the pointwise characterizations of derivatives of generalized Baskakov operators are described. |

| Keywords: | generalized Baskakov operators derivative modulus of continuity |
