The continuity, differentiability and differentiability of the function in higher mathematics are major and difficult content. This paper uses binary function continuous, differentiable, differentiable concepts and knowledge, the continuity of the binary function, conductivity, can differentiability discussed with the continuity of the function of one variable, differentiability, differentiable difference and connection.
