| Abstract: | The three-dimensional mapping that is to take point on the surface, seeking for intersecting lines, intersecting lines of teaching content, the students one to understand, but a more complex practical problems encountered was often impossible to start with; and take lessons in teaching more analysis and discussion of issues, put forward a three-dimensional points on the surface to find, seek for intersecting lines, intersecting lines, etc. as appropriate to focus on the method of instruction. Practice shows that this method can not only help solve these problems, but also to improve teaching efficiency. |
