| Abstract: | The pointwise approximation degree of the derivatives of the generalized Bernstein polynomials for derivable functions is estimated,and the direct and converse theorems of approximation are established,so the corresponding results of Bernstein polynomials are generalized. |

| Keywords: | generalized Bernstein polynomials derivative pointwise approximation |
