| Abstract: | This paper points out some flaws in commonly analytic geometry schoolbooks or teaching reference books,that the solution is not universal,algebraic conditions are not accurate and the equivalence is ignored in eliminate parameters etc,and puts forward some problems that should pay attention to in analytic geometry teaching. |
| Keywords: | Analytic Geometry teaching common perpendicular tangent sufficient and necessary condition equivalent property |
