1.集合的基本概念
①集合中元素的三大特征:确定性、互异性、无序性。
②常见集合的符号表示:
2.集合之间的基本关系
①空集是任何集合的子集,是任何非空集合的真子集。
②若集合A中含有n个元素,则其子集个数为2?,真子集个数为2?-1,非空真子集的个数为2?-2。
3.集合的基本运算
1.充分条件与必要条件
2.充分条件、必要条件与集合关系
若A={x|p(x)},B={x|q(x)},则
①若A?B,则p是q的充分条件;
②若A?B,则p是q的必要条件;
③若A=B,则p是q的充要条件;
④若A?B,则p是q的充分不必要条件;
⑤若A?B,则p是q的必要不充分条件;
⑥若A?B且A?B,则p是q的既不充分也不必要条件。
3.全称量词与存在量词
①全称命题:“对M中任意一个x,有p(x)成立”可用符号简记为:?x∈M,p(x)。
②特称命题:“存在M中的一个x?,使p(x?)成立”可用符号简记为:?x?∈M,p(x?)。
③含有一个量词的命题的否定。
