1、高考数学复习:历年高考数学易错知识点大汇总(最全)高考数学复习:历年高考数学易错知识点大汇总,最全, 高考君说: 数学是一座高山,哪怕是高考数学这样的小山丘,也让无数学子望其背而心戚戚,更有人混淆知识点,在里面兜兜转转浪费了精力和时间,满纸推算却只能挣得卷面分,看得自己也是好一阵心疼,高考君立马搬出高考数学易错知识点总结,希望能让大家少走一点弯路。收藏起来,一定有用! 集合与简单逻辑 1易错点 遗忘空集致误 错因分析:由于空集是仸何非空集合的真子集,因此,对于集合B,就有B=A,?B,B?,三种情况,在解题中如果思维不够缜密就有可能忽规了 B?这种情况,导致解题结果错误。尤其是在解含有参数的集
2、合问题时,更要充分注意当参数在某个范围内取值时所给的集合可能是空集这种情况。空集是一个特殊的集geographic location Yibin city is located in beautiful rich of abundance-Sichuan basin South margin, is located in n 103 ? 39 -105 ? 20 , latitude 27 ? 49 -29 ? 16 Zhijian; Yibin East and, Luzhou city, adjacent; North and zigong city development 12th a

9、全面。 2易错点 忽视集合元素的三性致误 错因分析:集合中的元素具有确定性、无序性、互异性,集合元素的三性中互异性对解题的影响最大,特别是带有字母参数的集合,实际上就隐含着对字母参数的一些要求。在解题时也可以先确定字母参数的范围后,再具体解决问题。 3易错点 四种命题的结构不明致误 错因分析:如果原命题是“若 A则B”,则这个命题的逆命题是“若B则A”,否命题是“若?A则?B”,逆否命题是“若?B则?A”。 这里面有两组等价的命题,即“原命题和它的逆否命题等价,否命题不逆命题等价”。在解答由一个命题写出该命题的其他形式的命题时,一定要明确四种命题的结构以及它们之间的等价关系。 另外,在否定一个
10、命题时,要注意全称命题的否定是特称命题,特称命题的否定是全称命题。如对“a,b都是偶数”的否定应该是“a,b不都是偶数”,而不应该是“a ,b都是奇数”。 4易错点 充分必要条件颠倒致误 geographic location Yibin city is located in beautiful rich of abundance-Sichuan basin South margin, is located in n 103 ? 39 -105 ? 20 , latitude 27 ? 49 -29 ? 16 Zhijian; Yibin East and, Luzhou city, adja
