对于很多含有字母的数学问题,它的解答过程都是会涉及分类讨论的思想。而在运用分类讨论思想的时候,对于分类标准的选择是最困难的,即我们该如何去使用分类讨论的思想。在对一道题目的解答过程中,分类讨论思想一般分为四步走:1.确定问题所讨论的对象以及所讨论的全域的范围;2.确定题目中的分类标准,合理地对选出的对象进行分类;3.按照分类标准,一个个地进行讨论,并将结果记录下来;4.对之前的结论进行总结和归纳。
For many mathematical problems with alphabets, the process of answering them involves the idea of categorical discussions. The use of taxonomy of thinking when the classification criteria for the selection is the most difficult, that is, how we should use the classification of thinking. In the process of answering a question, the idea of categorizing discussion is generally divided into four steps: 1. Determine the object to be discussed and the scope of the universe in question; 2. Determine the taxonomy of the question, Object classification; 3 according to the classification criteria, one by one to discuss and record the results; 4 on the conclusions of the previous summary and induction.
