集合作为一种常用数学工具是每年必考的内容之一.考查特点有二个:一个是集合本身的知识,如集合的交、并、补运算;二是集合语言与集合思想的运用,即把集合作为解决数学问题的工具,如函数的定义域、值域、方程与不等式的解集、曲线的相交问题等.近年来高考试题加
Set as a common mathematical tool is one of the content of the annual test.Examination has two characteristics: one is the collection of their own knowledge, such as the collection of the exchange, and make up computing; the second is the use of collective language and set theory, that is The collection as a tool to solve mathematical problems, such as the function of the domain, range, equation and inequality solution set, the intersection of the curve, etc. In recent years, the entrance examination plus
