| Abstract: |
| According to the characteristics of analytic geometry questions in college entrance examination question preparation, this paper proposes the idea using mapping geometry view to deal with analytic geometry problems in the mathematical questions in college entrance examinations in recent years, and finds higher geometry background of the questions by using vertex and polar line theory to understand the relation between point and line in analytic geometry of middle school, and by using vertex and polar line theory such as concept recognition, polar allocation principle and so on to enhance the study of fixed point and fixed line problems in analytic geometry. Only by using advanced theory, can middle school teachers have the ideas in the analytic geometry question preparation, can the students find the method to solve the problems, and can we find the application and guidance of higher mathematics to the teaching of middle schools. |
