解析几何教学中应注意的几个问题

Several Questions in Analytic Geometry Teaching

指出了解析几何常用教材、教学参考书中存在的解法不通用、应用代数条件不准确、消参数忽视等价性等几处瑕疵,相应地提出了解析几何教学中应该注意的几个问题.

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.
