2009年高考數(shù)學(xué)難點(diǎn)突破專(zhuān)題輔導(dǎo)三十二

難點(diǎn)32  極限及其運(yùn)算

極限的概念及其滲透的思想,在數(shù)學(xué)中占有重要的地位,它是人們研究許多問(wèn)題的工具.舊教材中原有的數(shù)列極限一直是歷年高考中重點(diǎn)考查的內(nèi)容之一.本節(jié)內(nèi)容主要是指導(dǎo)考生深入地理解極限的概念,并在此基礎(chǔ)上能正確熟練地進(jìn)行有關(guān)極限的運(yùn)算問(wèn)題.

●難點(diǎn)磁場(chǎng)

(★★★★)求6ec8aac122bd4f6e.

●案例探究

[例1]已知6ec8aac122bd4f6e(6ec8aac122bd4f6eaxb)=0,確定ab的值.

命題意圖:在數(shù)列與函數(shù)極限的運(yùn)算法則中,都有應(yīng)遵循的規(guī)則,也有可利用的規(guī)律,既有章可循,有法可依.因而本題重點(diǎn)考查考生的這種能力.也就是本知識(shí)的系統(tǒng)掌握能力.屬★★★★★級(jí)題目.

知識(shí)依托:解決本題的閃光點(diǎn)是對(duì)式子進(jìn)行有理化處理,這是求極限中帶無(wú)理號(hào)的式子常用的一種方法.

錯(cuò)解分析:本題難點(diǎn)是式子的整理過(guò)程繁瑣,稍不注意就有可能出錯(cuò).

技巧與方法:有理化處理.

解:6ec8aac122bd4f6e

要使上式極限存在,則1-a2=0,

當(dāng)1-a2=0時(shí),

6ec8aac122bd4f6e

6ec8aac122bd4f6e  解得6ec8aac122bd4f6e

[例2]設(shè)數(shù)列a1,a2,…,an,…的前n項(xiàng)的和Snan的關(guān)系是Sn=1-ban6ec8aac122bd4f6e,其中b是與n無(wú)關(guān)的常數(shù),且b≠-1.

(1)求anan1的關(guān)系式;

(2)寫(xiě)出用nb表示an的表達(dá)式;

(3)當(dāng)0<b<1時(shí),求極限6ec8aac122bd4f6eSn.

命題意圖:歷年高考中多出現(xiàn)的題目是與數(shù)列的通項(xiàng)公式,前n項(xiàng)和Sn等有緊密的聯(lián)系.有時(shí)題目是先依條件確定數(shù)列的通項(xiàng)公式再求極限,或先求出前n項(xiàng)和Sn再求極限,本題考查學(xué)生的綜合能力.屬★★★★★級(jí)題目.

知識(shí)依托:解答本題的閃光點(diǎn)是分析透題目中的條件間的相互關(guān)系.

錯(cuò)解分析:本題難點(diǎn)是第(2)中由(1)中的關(guān)系式猜想通項(xiàng)及n=1與n=2時(shí)的式子不統(tǒng)一性.

技巧與方法:抓住第一步的遞推關(guān)系式,去尋找規(guī)律.

解:(1)an=SnSn1=-b(anan1)-6ec8aac122bd4f6e=-b(anan1)+6ec8aac122bd4f6e (n≥2)

解得an=6ec8aac122bd4f6e (n≥2)

●錦囊妙計(jì)

1.學(xué)好數(shù)列的極限的關(guān)鍵是真正從數(shù)列的項(xiàng)的變化趨勢(shì)理解數(shù)列極限.

學(xué)好函數(shù)的極限的關(guān)鍵是真正從函數(shù)值或圖象上點(diǎn)的變化趨勢(shì)理解函數(shù)極限.

2.運(yùn)算法則中各個(gè)極限都應(yīng)存在.都可推廣到任意有限個(gè)極限的情況,不能推廣到無(wú)限個(gè).在商的運(yùn)算法則中,要注意對(duì)式子的恒等變形,有些題目分母不能直接求極限.

3.注意在平時(shí)學(xué)習(xí)中積累一些方法和技巧,如:

試題詳情

2009年高考數(shù)學(xué)難點(diǎn)突破專(zhuān)題輔導(dǎo)三十一

難點(diǎn)31  數(shù)學(xué)歸納法解題

數(shù)學(xué)歸納法是高考考查的重點(diǎn)內(nèi)容之一.類(lèi)比與猜想是應(yīng)用數(shù)學(xué)歸納法所體現(xiàn)的比較突出的思想,抽象與概括,從特殊到一般是應(yīng)用的一種主要思想方法.

●難點(diǎn)磁場(chǎng)

(★★★★)是否存在a、b、c使得等式1?22+2?32+…+n(n+1)2=6ec8aac122bd4f6e(an2+bn+c).

●案例探究

[例1]試證明:不論正數(shù)a、b、c是等差數(shù)列還是等比數(shù)列,當(dāng)n>1,nN*a、bc互不相等時(shí),均有:an+cn>2bn.

命題意圖:本題主要考查數(shù)學(xué)歸納法證明不等式,屬★★★★級(jí)題目.

知識(shí)依托:等差數(shù)列、等比數(shù)列的性質(zhì)及數(shù)學(xué)歸納法證明不等式的一般步驟.

錯(cuò)解分析:應(yīng)分別證明不等式對(duì)等比數(shù)列或等差數(shù)列均成立,不應(yīng)只證明一種情況.

技巧與方法:本題中使用到結(jié)論:(akck)(ac)>0恒成立(a、b、c為正數(shù)),從而ak+1+ck+1ak?c+ck?a.

證明:(1)設(shè)a、bc為等比數(shù)列,a=6ec8aac122bd4f6e,c=bq(q>0且q≠1)

an+cn=6ec8aac122bd4f6e+bnqn=bn(6ec8aac122bd4f6e+qn)>2bn

(2)設(shè)ab、c為等差數(shù)列,則2b=a+c猜想6ec8aac122bd4f6e>(6ec8aac122bd4f6e)n(n≥2且nN*)

下面用數(shù)學(xué)歸納法證明:

①當(dāng)n=2時(shí),由2(a2+c2)>(a+c)2,∴6ec8aac122bd4f6e

②設(shè)n=k時(shí)成立,即6ec8aac122bd4f6e

則當(dāng)n=k+1時(shí),6ec8aac122bd4f6e (ak+1+ck+1+ak+1+ck+1)

6ec8aac122bd4f6e(ak+1+ck+1+ak?c+ck?a)=6ec8aac122bd4f6e(ak+ck)(a+c)

>(6ec8aac122bd4f6e)k?(6ec8aac122bd4f6e)=(6ec8aac122bd4f6e)k+1

[例2]在數(shù)列{an}中,a1=1,當(dāng)n≥2時(shí),an,Sn,Sn6ec8aac122bd4f6e成等比數(shù)列.

(1)求a2,a3,a4,并推出an的表達(dá)式;

(2)用數(shù)學(xué)歸納法證明所得的結(jié)論;

(3)求數(shù)列{an}所有項(xiàng)的和.

命題意圖:本題考查了數(shù)列、數(shù)學(xué)歸納法、數(shù)列極限等基礎(chǔ)知識(shí).

知識(shí)依托:等比數(shù)列的性質(zhì)及數(shù)學(xué)歸納法的一般步驟.采用的方法是歸納、猜想、證明.

錯(cuò)解分析:(2)中,Sk=-6ec8aac122bd4f6e應(yīng)舍去,這一點(diǎn)往往容易被忽視.

技巧與方法:求通項(xiàng)可證明{6ec8aac122bd4f6e}是以{6ec8aac122bd4f6e}為首項(xiàng),6ec8aac122bd4f6e為公差的等差數(shù)列,進(jìn)而求得通項(xiàng)公式.

解:∵an,Sn,Sn6ec8aac122bd4f6e成等比數(shù)列,∴Sn2=an?(Sn6ec8aac122bd4f6e)(n≥2)                       (*)

(1)由a1=1,S2=a1+a2=1+a2,代入(*)式得:a2=-6ec8aac122bd4f6e

a1=1,a2=-6ec8aac122bd4f6e,S3=6ec8aac122bd4f6e+a3代入(*)式得:a3=-6ec8aac122bd4f6e

同理可得:a4=-6ec8aac122bd4f6e,由此可推出:an=6ec8aac122bd4f6e

(2)①當(dāng)n=1,2,3,4時(shí),由(*)知猜想成立.

②假設(shè)n=k(k≥2)時(shí),ak=-6ec8aac122bd4f6e成立

Sk2=-6ec8aac122bd4f6e?(Sk6ec8aac122bd4f6e)

∴(2k-3)(2k-1)Sk2+2Sk-1=0

Sk=6ec8aac122bd4f6e (舍)

Sk+12=ak+1?(Sk+16ec8aac122bd4f6e),得(Sk+ak+1)2=ak+1(ak+1+Sk6ec8aac122bd4f6e)

6ec8aac122bd4f6e

由①②知,an=6ec8aac122bd4f6e對(duì)一切nN成立.

(3)由(2)得數(shù)列前n項(xiàng)和Sn=6ec8aac122bd4f6e,∴S=6ec8aac122bd4f6eSn=0.

●錦囊妙記

(1)數(shù)學(xué)歸納法的基本形式

設(shè)P(n)是關(guān)于自然數(shù)n的命題,若

P(n0)成立(奠基)

具體常用數(shù)學(xué)歸納法證明:恒等式,不等式,數(shù)的整除性,幾何中計(jì)算問(wèn)題,數(shù)列的通項(xiàng)與和等.

設(shè)每售出一臺(tái)電冰箱,電器商獲利300元,如銷(xiāo)售不出而囤積于倉(cāng)庫(kù),則每臺(tái)每月需花保養(yǎng)費(fèi)用100元,問(wèn)電器商每月初購(gòu)進(jìn)多少臺(tái)電冰箱才能使自己月平均收益最大?

命題意圖:本題考查利用概率中的某些知識(shí)如期望來(lái)解決實(shí)際問(wèn)題.

知識(shí)依托:期望的概念及函數(shù)的有關(guān)知識(shí).

錯(cuò)解分析:在本題中,求Ey是一個(gè)難點(diǎn),稍有不慎,就將產(chǎn)生失誤.

技巧與方法:可借助概率分布、期望、方差等知識(shí)來(lái)解決日常生產(chǎn)生活中的實(shí)際問(wèn)題.

解:設(shè)x為月初電器商購(gòu)進(jìn)的冰箱臺(tái)數(shù),只須考慮1≤x≤12的情況,設(shè)電器商每月的收益為y元,則y是隨機(jī)變量ζ的函數(shù)且y=6ec8aac122bd4f6e,電器商平均每月獲益的平均數(shù),即數(shù)學(xué)期望為:Ey=300x(Px+Px+1+…+P12)+[300-100(x-1)]P1+[2×300-100(x-2)]P2+…+[300(x-1)-100]Px1

6ec8aac122bd4f6e

命題意圖:考查組合的概念及加法原理,屬★★★★★級(jí)題目.

知識(shí)依托:法一分成三類(lèi)方法;法二,間接法,去掉三點(diǎn)共線的組合.

錯(cuò)解分析:A中含有構(gòu)不成三角形的組合,如:C6ec8aac122bd4f6eC6ec8aac122bd4f6e中,包括O、BiBj;C6ec8aac122bd4f6eC6ec8aac122bd4f6e中,包含OAp、Aq,其中Ap、Aq,BiBj分別表示OA、OB邊上不同于O的點(diǎn);B漏掉△AiOBj;D有重復(fù)的三角形.如C6ec8aac122bd4f6eC6ec8aac122bd4f6e中有△AiOBj,C6ec8aac122bd4f6eC6ec8aac122bd4f6e中也有△AiOBj.

技巧與方法:分類(lèi)討論思想及間接法.

解法一:第一類(lèi)辦法:從OA邊上(不包括O)中任取一點(diǎn)與從OB邊上(不包括O)中任取兩點(diǎn),可構(gòu)造一個(gè)三角形,有C6ec8aac122bd4f6eC6ec8aac122bd4f6e個(gè);第二類(lèi)辦法:從OA邊上(不包括O)中任取兩點(diǎn)與OB邊上(不包括O)中任取一點(diǎn),與O點(diǎn)可構(gòu)造一個(gè)三角形,有C6ec8aac122bd4f6eC6ec8aac122bd4f6e個(gè);第三類(lèi)辦法:從OA邊上(不包括O)任取一點(diǎn)與OB邊上(不包括O)中任取一點(diǎn),與O點(diǎn)可構(gòu)造一個(gè)三角形,有C6ec8aac122bd4f6eC6ec8aac122bd4f6e個(gè).由加法原理共有N=C6ec8aac122bd4f6eC6ec8aac122bd4f6e+C6ec8aac122bd4f6eC6ec8aac122bd4f6e+C6ec8aac122bd4f6eC6ec8aac122bd4f6e個(gè)三角形.

解法二:從m+n+1中任取三點(diǎn)共有C6ec8aac122bd4f6e個(gè),其中三點(diǎn)均在射線OA(包括O點(diǎn)),有C6ec8aac122bd4f6e個(gè),三點(diǎn)均在射線OB(包括O點(diǎn)),有C6ec8aac122bd4f6e個(gè).所以,個(gè)數(shù)為N=C6ec8aac122bd4f6e-C6ec8aac122bd4f6e-C6ec8aac122bd4f6e個(gè).

答案:C

[例2]四名優(yōu)等生保送到三所學(xué)校去,每所學(xué)校至少得一名,則不同的保送方案的總數(shù)是_________.

命題意圖:本題主要考查排列、組合、乘法原理概念,以及靈活應(yīng)用上述概念處理數(shù)學(xué)問(wèn)題的能力,屬★★★★級(jí)題目.

知識(shí)依托:排列、組合、乘法原理的概念.

錯(cuò)解分析:根據(jù)題目要求每所學(xué)校至少接納一位優(yōu)等生,常采用先安排每學(xué)校一人,而后將剩的一人送到一所學(xué)校,故有3A6ec8aac122bd4f6e種.忽略此種辦法是:將同在一所學(xué)校的兩名學(xué)生按進(jìn)入學(xué)校的前后順序,分為兩種方案,而實(shí)際題目中對(duì)進(jìn)入同一所學(xué)校的兩名學(xué)生是無(wú)順序要求的.

技巧與方法:解法一,采用處理分堆問(wèn)題的方法.解法二,分兩次安排優(yōu)等生,但是進(jìn)入同一所學(xué)校的兩名優(yōu)等生是不考慮順序的.

解法一:分兩步:先將四名優(yōu)等生分成2,1,1三組,共有C6ec8aac122bd4f6e種;而后,對(duì)三組學(xué)生安排三所學(xué)校,即進(jìn)行全排列,有A33種.依乘法原理,共有N=C6ec8aac122bd4f6e6ec8aac122bd4f6e =36(種).

解法二:分兩步:從每個(gè)學(xué)校至少有一名學(xué)生,每人進(jìn)一所學(xué)校,共有A6ec8aac122bd4f6e種;而后,再將剩余的一名學(xué)生送到三所學(xué)校中的一所學(xué)校,有3種.值得注意的是:同在一所學(xué)校的兩名學(xué)生是不考慮進(jìn)入的前后順序的.因此,共有N=6ec8aac122bd4f6eA6ec8aac122bd4f6e?3=36(種).

●錦囊妙記

排列與組合的應(yīng)用題,是高考常見(jiàn)題型,其中主要考查有附加條件的應(yīng)用問(wèn)題.解決這類(lèi)問(wèn)題通常有三種途徑:(1)以元素為主,應(yīng)先滿(mǎn)足特殊元素的要求,再考慮其他元素.(2)以位置為主考慮,即先滿(mǎn)足特殊位置的要求,再考慮其他位置.(3)先不考慮附加條件,計(jì)算出排列或組合數(shù),再減去不符合要求的排列數(shù)或組合數(shù).前兩種方式叫直接解法,后一種方式叫間接解法.

在求解排列與組合應(yīng)用問(wèn)題時(shí),應(yīng)注意:

(1)把具體問(wèn)題轉(zhuǎn)化或歸結(jié)為排列或組合問(wèn)題;

(2)通過(guò)分析確定運(yùn)用分類(lèi)計(jì)數(shù)原理還是分步計(jì)數(shù)原理;

(3)分析題目條件,避免“選取”時(shí)重復(fù)和遺漏;

(4)列出式子計(jì)算和作答.

解排列與組合應(yīng)用題常用的方法有:直接計(jì)算法與間接計(jì)算法;分類(lèi)法與分步法;元素分析法和位置分析法;插空法和捆綁法等八種.

經(jīng)常運(yùn)用的數(shù)學(xué)思想是:

①分類(lèi)討論思想;②轉(zhuǎn)化思想;③對(duì)稱(chēng)思想.

3、A  本題考查考生運(yùn)用介詞和比較級(jí)的能力。For在這里是“就……而言”的意思,而第二個(gè)選項(xiàng)要抓住信息詞still在此處的妙用,它是用來(lái)修飾比較級(jí)的,加上上文的cold,在此處就不難選擇colder了。

4、D  本題考查不定代詞的本意區(qū)別及其與語(yǔ)境綜合運(yùn)用。此處none指的是not any vinegar,也就是說(shuō),此處可以這樣理解:I’m sorry to say that I didn’t put any vinegar in the soup, because I forgot it.

5、B  本題考查考生在語(yǔ)境中靈活運(yùn)用、辨析短語(yǔ)用法的能力,此處seldom,if ever是一個(gè)短語(yǔ),是“從不,決不”的意思。

6、B  本題however you like相當(dāng)于in whatever way you like,根據(jù)語(yǔ)境,不難判斷出B為正確答案。
