| Abstract: | Mathematica Software has a powerful drawing and program design functions, in teaching of the quadric ,we use mathematica software drawing and programming functions, to describe quadric and the coordinates of the surface of the plane from the intersection line, say, the cut-off marks,dynamic process of change,which will strengthen the teaching of the visual content and students＇understanding of the quadric graphics. |
