难点32 极限及其运算
极限的概念及其渗透的思想,在数学中占有重要的地位,它是人们研究许多问题的工具.旧教材中原有的数列极限一直是历年高考中重点考查的内容之一.本节内容主要是指导考生深入地理解极限的概念,并在此基础上能正确熟练地进行有关极限的运算问题.
●难点磁场
●案例探究
命题意图:在数列与函数极限的运算法则中,都有应遵循的规则,也有可利用的规律,既有章可循,有法可依.因而本题重点考查考生的这种能力.也就是本知识的系统掌握能力.属★★★★★级题目.
知识依托:解决本题的闪光点是对式子进行有理化处理,这是求极限中带无理号的式子常用的一种方法.
错解分析:本题难点是式子的整理过程繁琐,稍不注意就有可能出错.
技巧与方法:有理化处理.
要使上式极限存在,则1-a2=0,
当1-a2=0时,
[例2]设数列a1,a2,…,an,…的前n项的和Sn和an的关系是Sn=1-ban-,其中b是与n无关的常数,且b≠-1.
(1)求an和an-1的关系式;
(2)写出用n和b表示an的表达式;
命题意图:历年高考中多出现的题目是与数列的通项公式,前n项和Sn等有紧密的联系.有时题目是先依条件确定数列的通项公式再求极限,或先求出前n项和Sn再求极限,本题考查学生的综合能力.属★★★★★级题目.
知识依托:解答本题的闪光点是分析透题目中的条件间的相互关系.
错解分析:本题难点是第(2)中由(1)中的关系式猜想通项及n=1与n=2时的式子不统一性.
技巧与方法:抓住第一步的递推关系式,去寻找规律.
解:(1)an=Sn-Sn-1=-b(an-an-1)-=-b(an-an-1)+ (n≥2)
●锦囊妙计
1.学好数列的极限的关键是真正从数列的项的变化趋势理解数列极限.
学好函数的极限的关键是真正从函数值或图象上点的变化趋势理解函数极限.
2.运算法则中各个极限都应存在.都可推广到任意有限个极限的情况,不能推广到无限个.在商的运算法则中,要注意对式子的恒等变形,有些题目分母不能直接求极限.
3.注意在平时学习中积累一些方法和技巧,如:

难点31 数学归纳法解题
数学归纳法是高考考查的重点内容之一.类比与猜想是应用数学归纳法所体现的比较突出的思想,抽象与概括,从特殊到一般是应用的一种主要思想方法.
●难点磁场
(★★★★)是否存在a、b、c使得等式1?22+2?32+…+n(n+1)2=(an2+bn+c).
●案例探究
[例1]试证明:不论正数a、b、c是等差数列还是等比数列,当n>1,n∈N*且a、b、c互不相等时,均有:an+cn>2bn.
命题意图:本题主要考查数学归纳法证明不等式,属★★★★级题目.
知识依托:等差数列、等比数列的性质及数学归纳法证明不等式的一般步骤.
错解分析:应分别证明不等式对等比数列或等差数列均成立,不应只证明一种情况.
技巧与方法:本题中使用到结论:(ak-ck)(a-c)>0恒成立(a、b、c为正数),从而ak+1+ck+1>ak?c+ck?a.
证明:(1)设a、b、c为等比数列,a=,c=bq(q>0且q≠1)
(2)设a、b、c为等差数列,则2b=a+c猜想>()n(n≥2且n∈N*)
下面用数学归纳法证明:
则当n=k+1时, (ak+1+ck+1+ak+1+ck+1)
>(ak+1+ck+1+ak?c+ck?a)=(ak+ck)(a+c)
[例2]在数列{an}中,a1=1,当n≥2时,an,Sn,Sn-成等比数列.
(1)求a2,a3,a4,并推出an的表达式;
(2)用数学归纳法证明所得的结论;
(3)求数列{an}所有项的和.
命题意图:本题考查了数列、数学归纳法、数列极限等基础知识.
知识依托:等比数列的性质及数学归纳法的一般步骤.采用的方法是归纳、猜想、证明.
技巧与方法:求通项可证明{}是以{}为首项,为公差的等差数列,进而求得通项公式.
解:∵an,Sn,Sn-成等比数列,∴Sn2=an?(Sn-)(n≥2) (*)
(1)由a1=1,S2=a1+a2=1+a2,代入(*)式得:a2=-
(2)①当n=1,2,3,4时,由(*)知猜想成立.
∴(2k-3)(2k-1)Sk2+2Sk-1=0
由Sk+12=ak+1?(Sk+1-),得(Sk+ak+1)2=ak+1(ak+1+Sk-)
●锦囊妙记
(1)数学归纳法的基本形式
设P(n)是关于自然数n的命题,若
1°P(n0)成立(奠基)
2°假设P(k)成立(k≥n0),可以推出P(k+1)成立(归纳),则P(n)对一切大于等于n0的自然数n都成立.
(2)数学归纳法的应用
具体常用数学归纳法证明:恒等式,不等式,数的整除性,几何中计算问题,数列的通项与和等.

难点30 概 率
概率是高考的重点内容之一,尤其是新增的随机变量这部分内容.要充分注意一些重要概念的实际意义,理解概率处理问题的基本思想方法.
●难点磁场
(★★★★★)如图,用A、B、C三类不同的元件连接成两个系统N1、N2,当元件A、B、C都正常工作时,系统N1正常工作;当元件A正常工作且元件B、C至少有一个正常工作时,系统N2正常工作.已知元件A、B、C正常工作的概率依次为0.80,0.90,0.90,分别求系统N1,N2正常工作的概率P1、P2.
●案例探究
[例1](★★★★★)有一容量为50的样本,数据的分组及各组的频率数如下:
[10,15]4 [30,359 [15,205 [35,408 [20,2510 [40,453 [25,3011
(1)列出样本的频率分布表(含累积频率);
(2)画出频率分布直方图和累积频率的分布图.
命题意图:本题主要考查频率分布表,频率分布直方图和累积频率的分布图的画法.
知识依托:频率、累积频率的概念以及频率分布表、直方图和累积频率分布图的画法.
错解分析:解答本题时,计算容易出现失误,且要注意频率分布与累积频率分布的区别.
技巧与方法:本题关键在于掌握三种表格的区别与联系.
解:(1)由所给数据,计算得如下频率分布表

ζ

3
……
12
P
……
设每售出一台电冰箱,电器商获利300元,如销售不出而囤积于仓库,则每台每月需花保养费用100元,问电器商每月初购进多少台电冰箱才能使自己月平均收益最大?
命题意图:本题考查利用概率中的某些知识如期望来解决实际问题.
知识依托:期望的概念及函数的有关知识.
错解分析:在本题中,求Ey是一个难点,稍有不慎,就将产生失误.
技巧与方法:可借助概率分布、期望、方差等知识来解决日常生产生活中的实际问题.
解:设x为月初电器商购进的冰箱台数,只须考虑1≤x≤12的情况,设电器商每月的收益为y元,则y是随机变量ζ的函数且y=,电器商平均每月获益的平均数,即数学期望为:Ey=300x(Px+Px+1+…+P12)+[300-100(x-1)]P1+[2×300-100(x-2)]P2+…+[300(x-1)-100]Px-1
由于x∈N,故可求出当x=9或x=10时,也即电器商月初购进9台或10台电冰箱时,收益最大.

难点29 排列、组合的应用问题
排列、组合是每年高考必定考查的内容之一,纵观全国高考数学题,每年都有1~2道排列组合题,考查排列组合的基础知识、思维能力.
●难点磁场
(★★★★★)有五张卡片,它们的正、反面分别写0与1,2与3,4与5,6与7,8与9,将其中任意三张并排放在一起组成三位数,共可组成多少个不同的三位数?
●案例探究
[例1]在∠AOB的OA边上取m个点,在OB边上取n个点(均除O点外),连同O点共m+n+1个点,现任取其中三个点为顶点作三角形,可作的三角形有( )
命题意图:考查组合的概念及加法原理,属★★★★★级题目.
知识依托:法一分成三类方法;法二,间接法,去掉三点共线的组合.
错解分析:A中含有构不成三角形的组合,如:CC中,包括O、Bi、Bj;CC中,包含O、Ap、Aq,其中Ap、Aq,Bi、Bj分别表示OA、OB边上不同于O的点;B漏掉△AiOBj;D有重复的三角形.如CC中有△AiOBj,CC中也有△AiOBj.
技巧与方法:分类讨论思想及间接法.
解法一:第一类办法:从OA边上(不包括O)中任取一点与从OB边上(不包括O)中任取两点,可构造一个三角形,有CC个;第二类办法:从OA边上(不包括O)中任取两点与OB边上(不包括O)中任取一点,与O点可构造一个三角形,有CC个;第三类办法:从OA边上(不包括O)任取一点与OB边上(不包括O)中任取一点,与O点可构造一个三角形,有CC个.由加法原理共有N=CC+CC+CC个三角形.
解法二:从m+n+1中任取三点共有C个,其中三点均在射线OA(包括O点),有C个,三点均在射线OB(包括O点),有C个.所以,个数为N=C-C-C个.
答案:C
[例2]四名优等生保送到三所学校去,每所学校至少得一名,则不同的保送方案的总数是_________.
命题意图:本题主要考查排列、组合、乘法原理概念,以及灵活应用上述概念处理数学问题的能力,属★★★★级题目.
知识依托:排列、组合、乘法原理的概念.
错解分析:根据题目要求每所学校至少接纳一位优等生,常采用先安排每学校一人,而后将剩的一人送到一所学校,故有3A种.忽略此种办法是:将同在一所学校的两名学生按进入学校的前后顺序,分为两种方案,而实际题目中对进入同一所学校的两名学生是无顺序要求的.
技巧与方法:解法一,采用处理分堆问题的方法.解法二,分两次安排优等生,但是进入同一所学校的两名优等生是不考虑顺序的.
解法一:分两步:先将四名优等生分成2,1,1三组,共有C种;而后,对三组学生安排三所学校,即进行全排列,有A33种.依乘法原理,共有N=C =36(种).
解法二:分两步:从每个学校至少有一名学生,每人进一所学校,共有A种;而后,再将剩余的一名学生送到三所学校中的一所学校,有3种.值得注意的是:同在一所学校的两名学生是不考虑进入的前后顺序的.因此,共有N=A?3=36(种).
答案:36
●锦囊妙记
排列与组合的应用题,是高考常见题型,其中主要考查有附加条件的应用问题.解决这类问题通常有三种途径:(1)以元素为主,应先满足特殊元素的要求,再考虑其他元素.(2)以位置为主考虑,即先满足特殊位置的要求,再考虑其他位置.(3)先不考虑附加条件,计算出排列或组合数,再减去不符合要求的排列数或组合数.前两种方式叫直接解法,后一种方式叫间接解法.
在求解排列与组合应用问题时,应注意:
(1)把具体问题转化或归结为排列或组合问题;
(2)通过分析确定运用分类计数原理还是分步计数原理;
(3)分析题目条件,避免“选取”时重复和遗漏;
(4)列出式子计算和作答.
解排列与组合应用题常用的方法有:直接计算法与间接计算法;分类法与分步法;元素分析法和位置分析法;插空法和捆绑法等八种.
经常运用的数学思想是:
①分类讨论思想;②转化思想;③对称思想.
