| Abstract: | The definition of approximated remainders with generalized Baskakov operator was introduced,the remainders were discussed for three kinds of functions,and three forms of estimated remainders were obtained,so that the results became even more generalized.Meantime,the available theorem of approximation degree of generalized Baskakov operator was improved. |
