高考数学将分类与整合思想的考查放在了比较重要的位置,主要以解答题的形式出现。要求考生明确何种问题需要分类,如何分类,分类后如何研究,最后如何整合。考查的主要题型是含有字母参数的数学问题。分类讨论的渊源很多,下面以引发分类讨论的不同渊源进行分类解析。一、由数学概念引起的分类讨论。如绝对值的定义、二次函数的定义、直线与平面所成的角、直线的倾斜角等。 College entrance examination mathematics classification and integration of thinking on the more important position, mainly in the form of answers to questions. Ask candidates to clarify what kind of problems need to be classified, how to classify, how to study after classification, and finally how to integrate. The main type of test is the mathematical problem with alphabetic parameters. There are many sources of taxonomy discussion, the following classification analysis to trigger the classification of different origins. First, the concept of mathematics caused by the classification discussion. Such as the definition of absolute value, the definition of quadratic function, the angle formed by the straight line and the plane, the inclination angle of the straight line, and the like.
