| Abstract: | This paper gives the definitions of the limit function and the sum function and discusses the relation between them. And the continuity of the limit function and the sum function are discussed. The necessary condition for convergent series is obtained by using limit function and the continuity of the limit function and the sum function is discussed as well. Finally the sufficient condition for a sequence of the continuous partial sums of the series is got. |
