1、2023年高一上册知识点总结(含五篇) 第一篇:高一上册学问点总结 学问是符合文明方向的,人类对物质世界以及精神世界探究的结果总和。下面是我整理的高一上册学问点总结,欢迎阅读参考! 一、高一上册学问点总结 一般我们把不含任何元素的集合叫做空集。 集合的分类: 1按元素属性分类,如点集,数集。2按元素的个数多少,分为有/无限集 关于集合的概念: 1确定性:作为一个集合的元素,必需是确定的,这就是说,不能确定的对象就不能构成集合,也就是说,给定一个集合,任何一个对象是不是这个集合的元素也就确定了。 2互异性:对于一个给定的集合,集合中的元素确定是不同的或说是互异的,这就是说,集合中的任何两个元素都
2、是不同的对象,相同的对象归入同一个集合时只能算作集合的一个元素。 3无序性:推断一些对象时候构成集合,关键在于看这些对象是否有明确的标准。 集合可以根据它含有的元素的个数分为两类: 含有有限个元素的集合叫做有限集,含有无限个元素的集合叫做无限集。 非负整数全体构成的集合,叫做自然数集,记作N; 在自然数集内解除0的集合叫做正整数集,记作N+或N*; 整数全体构成的集合,叫做整数集,记作Z; 有理数全体构成的集合,叫做有理数集,记作Q;有理数是整数和分数的统称,一切有理数都可以化成分数的形式。 实数全体构成的集合,叫做实数集,记作R。包括有理数和无理数。其中无理数就是无限不循环小数,有理数就包括
3、整数和分数。数学上,实数直观地定义为和数轴上的点一一对应的数。 二、高一上册学问点总结 1.列举法:假如一个集合是有限集,元素又不太多,常常把集合的全部元素都列举出来,写在花括号“ 内表示这个集合,例如,由两个元素0,1构成的集合可表示为0,1.有些集合的元素较多,元素的排列又呈现确定的规律,在不致于发生误会的状况下,也可以列出几个元素作为代表,其他元素用省略号表示。 例如:不大于100的自然数的全体构成的集合,可表示为0,1,2,3,100.无限集有时也用上述的列举法表示,例如,自然数集N可表示为1,2,3,n,.2.描述法:一种更有效地描述集合的方法,是用集合中元素的特征性质来描述。 例如
4、:正偶数构成的集合,它的每一个元素都具有性质:“能被2整除,且大于0 而这个集合外的其他元素都不具有这种性质,因此,我们可以用上述性质把正偶数集合表示为 xRx能被2整除,且大于0或xRx=2n,nN+,大括号内竖线左边的X表示这个集合的随便一个元素,元素X从实数集合中取值,在竖线右边写出只有集合内的元素x才具有的性质。 一般地,假如在集合I中,属于集合A的随便一个元素x都具有性质p(x),而不属于集合A的元素都不具有的性质p(x),则性质p(x)叫做集合A的一个特征性质。于是,集合A可以用它的性质p(x)描述为xIp(x) 它表示集合A是由集合I中具有性质p(x)的全部元素构成的,这种表示集
5、合的方法,叫做特征性质描述法,简称描述法。 例如:集合A=xRx2-1=0的特征是X2-1=0 其次篇:高一英语学问点总结(上册) 高一英语学问点 重点词组: 1.fond of “宠爱,爱好 接名词、代词或动词的-ing形式。例如: Hes fond of swimming.他宠爱游泳。 Are you fond of fresh vegetables.你宠爱簇新蔬菜吗?
