集合,是现代数学中的一个最基本的概念.集合概念渗透到数学各个分支中,对培养运用集合观念解题的能力,提高数学素养是大有好处的.集合问题多与函数、方程、不等式和解析几何有关,解答此类问题时要注意各类知识的相互转化、融会贯通与综合运用.下面就集合中的参数问题分类解析,供读者参考. Collection is a basic concept in modern mathematics. The concept of collection permeates into all branches of mathematics. It is of great benefit to develop the ability to use the concept of set to solve problems and improve the quality of mathematics. The set of problems and functions, equations, inequalities Relevant to analytical geometry, to answer such questions should pay attention to the mutual transformation of various types of knowledge, integration and comprehensive utilization. The following analysis of the classification of the parameters of the problem, for readers reference.
