解析几何是用代数方法研究几何问题的学科。在解析几何的解题过程中,无论是计算题还是证明题,我们通常总是将已知的几何条件表示成代数式子,然后经过适当的代数运算,最后回到所需的几何目标。因此,在解题过程中,尽量减小计算量,往往成为能否迅速、准确地解题的关键。现将我们在教学中的体会介绍如下: Analytic geometry is a discipline that uses algebraic methods to study geometric problems. In the process of solving a problem in analytical geometry, whether it is a calculation problem or a proof problem, we usually represent the known geometric conditions as algebraic expressions, then perform appropriate algebraic operations, and finally return to the desired geometric target. Therefore, in the problem-solving process, reducing the amount of calculation as much as possible is often the key to whether the problem can be solved quickly and accurately. Now we introduce our experience in teaching as follows:
