3．對于集合當(dāng)時(shí)，你是否注意到一個(gè)極端情況：或,求集合的子集時(shí),是否忘記了?當(dāng)研究的時(shí)候, 你是否考慮到的情形?當(dāng)時(shí), 你是否注意到的情形?

2．數(shù)形結(jié)合是解集合問題的常用方法：解題時(shí)要盡可能地借助數(shù)軸、直角坐標(biāo)系或韋恩圖等工具，將抽象的代數(shù)問題具體化、形象化、直觀化，然后利用數(shù)形結(jié)合的思想方法解決；

1．理解集合中元素的意義是解決集合問題的關(guān)鍵：弄清以及數(shù)集中元素是函數(shù)關(guān)系中自變量的取值？還是因變量的取值？還是曲線上的點(diǎn)？… ；看清描述法表示的集合中的元素是數(shù)集還是點(diǎn)集。
