篇5：高二上册数学知识点
一、随机事件
主要掌握好(三四五)
(1)事件的三种运算：并(和)、交(积)、差;注意差A-B可以表示成A与B的逆的积。
(2)四种运算律：交换律、结合律、分配律、德莫根律。
(3)事件的五种关系：包含、相等、互斥(互不相容)、对立、相互独立。
二、概率定义
(1)统计定义：频率稳定在一个数附近，这个数称为事件的概率;
(2)古典定义：要求样本空间只有有限个基本事件，每个基本事件出现的可能性相等，则事件A所含基本事件个数与样本空间所含基本事件个数的比称为事件的古典概率;
(3)几何概率：样本空间中的元素有无穷多个，每个元素出现的可能性相等，则可以将样本空间看成一个几何图形，事件A看成这个图形的子集，它的概率通过子集图形的大小与样本空间图形的大小的比来计算;
(4)公理化定义：满足三条公理的任何从样本空间的子集集合到[0，1]的映射。
三、概率性质与公式
(1)加法公式：P(A+B)=p(A)+P(B)-P(AB)，特别地，如果A与B互不相容，则P(A+B)=P(A)+P(B);
(2)差：P(A-B)=P(A)-P(AB)，特别地，如果B包含于A，则P(A-B)=P(A)-P(B);
(3)乘法公式：P(AB)=P(A)P(B|A)或P(AB)=P(A|B)P(B)，特别地，如果A与B相互独立，则P(AB)=P(A)P(B);
(4)全概率公式：P(B)=∑P(Ai)P(B|Ai).它是由因求果，
贝叶斯公式：P(Aj|B)=P(Aj)P(B|Aj)/∑P(Ai)P(B|Ai).它是由果索因;
如果一个事件B可以在多种情形(原因)A1,A2,....,An下发生，则用全概率公式求B发生的概率;如果事件B已经发生，要求它是由Aj引起的概率，则用贝叶斯公式.
(5)二项概率公式：Pn(k)=C(n,k)p^k(1-p)^(n-k),k=0,1,2,....,n.当一个问题可以看成n重贝努力试验(三个条件：n次重复，每次只有A与A的逆可能发生，各次试验结果相互独立)时，要考虑二项概率公式.
数学的学习方法技巧
一、课内重视听讲，课后及时复习。
课堂上特别要抓住基础知识和基本技能的学习，课后要及时复习不留疑点。
首先要在做各种习题之前将老师所讲的知识点回忆一遍，正确掌握各类公式的推理过程，尽量回忆而不采用不清楚立即翻书之举。认真独立完成作业，勤于思考，对于有些题目由于自己的思路不清，一时难以解出，应让自己冷静下来认真分析题目，尽量自己解决。在每个阶段的学习中要进行整理和归纳总结，把知识的点、线、面结合起来交织成知识网络，纳入自己的知识体系。
二、适当多做题，养成良好的解题习惯。
1、要想学好数学，多做题目是必须的，熟悉掌握各种题型的解题思路。
2、刚开始要从基础题入手，以课本上的习题为准，反复练习打好基础，再找一些课外的习题，以帮助开拓思路，提高自己的分析、解决能力，掌握一般的.解题规律。
3、对于一些易错题，可备有错题集，写出自己的解题思路和正确的解题过程两者一起比较找出自己的错误所在，以便及时更正。
4、在平时要养成良好的解题习惯。让自己的精力高度集中，使大脑兴奋，思维敏捷，能够进入最佳状态，在考试中能运用自如。实践证明：越到关键时候，你所表现的解题习惯与平时练习无异。
有些同学平时做作业都会做，可一到考试就犯不是算错数，就是看错题等等低级错误。这是因为平时解题时随便、粗心、大意等，所以小朋友平时要养成良好的解题习惯是非常重要的!
三、调整心态，正确对待考试。
1、首先，应把主要精力放在基础知识、基本技能、基本方法这三个方面上，因为每次考试占绝大部分的也是基础性的题目，而对于那些难题及综合性较强的题目作为调剂，认真思考，尽量让自己理出头绪，做完题后要总结归纳。
2、调整好自己的心态，使自己在任何时候镇静，思路有条不紊，克服浮躁的情绪。特别是对自己要有信心，永远鼓励自己，除了自己，谁也不能把我打倒，要有自己不垮，谁也不能打垮我的自豪感。
3、考试前要做好准备，练练常规题，把自己的思路展开，在保证正确率的前提下提高解题速度。对于一些容易的基础题要有十二分把握拿全分;对于一些难题，也要尽量拿分，考试中要使自己的水平正常甚至超常发挥。
由此可见，要把数学学好就得找到适合自己的学习方法，了解数学学科的特点，使自己进入数学的广阔天地中去。
