分类讨论思想是解决问题的一种思维方法,也是一种数学思想,这种思想在简化研究对象发展思维方面起着重要作用,在中考命题中占有重要地位.所谓分类讨论,就是在我们所遇到的数学问题中,把所有研究的问题根据题目的特点和要求,分成若干类,转化成若干个小问题来解决,最后综合各类结果得到整个问题的解,这一思想方法,我们称之为“分类讨论思想”.
Classified discussion is a thinking method to solve the problem, but also a mathematical thought, which plays an important role in simplifying the thinking of the development of the research object, occupies an important position in the senior high school entrance examination.The so-called classification discussion is in our encounter According to the characteristics and requirements of the topic, the mathematical problems to be solved are divided into a number of categories according to the characteristics and requirements of the topic, and the problems are solved by several small problems. Finally, the solution of the entire problem is obtained by combining various kinds of results. The way of thinking we call it For the “classification of thinking”.
