解析几何是用代数方法研究几何问题的数学学科,在遇到解析几何的计算题或证明题时,我们通常是将已知的几何条件表示成代数式子,通过代数运算来解决问题,这可以说是解析几何的本质,但代数运算的运算量通常比较大,如果不分清问题形势,一味强调运算,不仅不能调动学生的积极性,而且有把获取数学知识、形成数学技能和能 Analytic geometry is a mathematical discipline that uses algebraic methods to study geometry problems. In the case of computational or proof questions that solve analytic geometry, we usually represent known geometric conditions as algebraic equations, solving problems by algebraic operations, which we can say Is the essence of analytic geometry. However, the computational complexity of algebraic operations is usually rather large. If you do not understand the problem situation and emphasize computing, you can not only arouse students’ enthusiasm, but also acquire mathematical knowledge and form mathematical skills
