分类讨论是一种重要的数学思想,在中学数学中占有重要的位置。当然,利用分类讨论思想解题,有时难免会使问题的解决过程变得冗长。因此,我们希望在解题过程中尽量避免由人为因素引起的分类讨论。在解题过程中,如何避免人为引起的分类讨论。下面,我提出几点建议,供学生复习时参考。一、绕开讨论因素对有些从表面上似乎需要分类讨论的数学问题,只要能够借助相关的数学概念、性质等就可以绕开引起分类讨论的因素,从而
Classification discussion is an important mathematical thought, occupies an important position in high school mathematics. Of course, the use of taxonomy to solve problems, sometimes inevitably make the problem solving process becomes lengthy. Therefore, we hope to avoid category discussions caused by human factors in the process of solving problems. In the process of solving problems, how to avoid human-induced classification discussion. Below, I make a few suggestions for students to review reference. First, to circumvent the discussion of factors Some seemingly need to be discussed in terms of mathematical problems, as long as the relevant mathematical concepts can be used to bypass the causes of classification and discussion of the factors that
