分类讨论思想在现阶段的高中数学解题过程应用较为普遍,这也是高中数学教学的重点难点,学生在应用过程中普遍存在着一定的问题,对于如何分类、按照什么标准以及分类是否完整等方面都存在着一定的问题。本文基于这一状况,对高中数学应用分类讨论思想解题进行了一定的探讨。 The classification discussion thought is widely used in the current high school mathematics problem solving process. This is also the key point of high school mathematics teaching. There are some common problems in the application process of students, how to classify, according to what criteria and whether the classification is complete There are some problems. Based on this situation, this article explores the problem of classification discussion in high school mathematics application.
