） Abstract： In this paper, we first denominate bifunction xy/(x^2+y^2) as sine-line curved face and describe its graphics visually by the method of intercept of a plane of concentric cylinder
We point out two of its characteristics and study the mathematical characters of the sine-line curved face
We introduce a courseware which can be demonstrated dynamically and give three conclusions finally
