分类讨论是高中数学一大重要解题思想。分类讨论要求解题者着眼整体,纵观全局,分步骤,有次序的进行解题。对于题目中的隐含条件要统统考虑到位。分类讨论思想是高考必考的一大数学思想方法,了解分类讨论原则,掌握讨论方法,可有效提高解题速度与正确率。本文就高中数学解题中的分类谈论思想做了简要概述,结合例题谈论其重要性。
Category discussion is a major high school mathematics problem-solving ideas. Category discussion requires solvers to focus on the whole, look at the overall situation, step by step, orderly problem-solving. For the subject of implicit conditions should be considered for all. The taxonomy discussion is a major mathematical method that the college entrance examination must take to understand the principles of classification and discussion and to master the discussion methods, which can effectively improve the speed and accuracy of problem-solving. This article gives a brief overview of the theory of categorical discourse in high school mathematics problem solving, and discusses the importance of it in combination with the examples.
