2009年高考數(shù)學(xué)難點(diǎn)突破專題輔導(dǎo)三十四

難點(diǎn)34  導(dǎo)數(shù)的運(yùn)算法則及基本公式應(yīng)用

導(dǎo)數(shù)是中學(xué)限選內(nèi)容中較為重要的知識(shí),本節(jié)內(nèi)容主要是在導(dǎo)數(shù)的定義,常用求等公式.四則運(yùn)算求導(dǎo)法則和復(fù)合函數(shù)求導(dǎo)法則等問題上對(duì)考生進(jìn)行訓(xùn)練與指導(dǎo).

●難點(diǎn)磁場

(★★★★★)已知曲線Cy=x3-3x2+2x,直線l:y=kx,且lC切于點(diǎn)(x0,y0)(x0≠0),求直線l的方程及切點(diǎn)坐標(biāo).

●案例探究

[例1]求函數(shù)的導(dǎo)數(shù):

6ec8aac122bd4f6e

命題意圖:本題3個(gè)小題分別考查了導(dǎo)數(shù)的四則運(yùn)算法則,復(fù)合函數(shù)求導(dǎo)的方法,以及抽象函數(shù)求導(dǎo)的思想方法.這是導(dǎo)數(shù)中比較典型的求導(dǎo)類型,屬于★★★★級(jí)題目.

知識(shí)依托:解答本題的閃光點(diǎn)是要分析函數(shù)的結(jié)構(gòu)和特征,挖掘量的隱含條件,將問題轉(zhuǎn)化為基本函數(shù)的導(dǎo)數(shù).

錯(cuò)解分析:本題難點(diǎn)在求導(dǎo)過程中符號(hào)判斷不清,復(fù)合函數(shù)的結(jié)構(gòu)分解為基本函數(shù)出差錯(cuò).

技巧與方法:先分析函數(shù)式結(jié)構(gòu),找準(zhǔn)復(fù)合函數(shù)的式子特征,按照求導(dǎo)法則進(jìn)行求導(dǎo).

6ec8aac122bd4f6e

 

(2)解:y=μ3,μ=axbsin2ωx,μ=avby

v=x,y=sinγ  γx

y′=(μ3)′=3μ2?μ′=3μ2(avby)′

=3μ2(av′-by′)=3μ2(av′-byγ′)

=3(axbsin2ωx)2(abωsin2ωx)

(3)解法一:設(shè)y=f(μ),μ=6ec8aac122bd4f6e,v=x2+1,則

yx=yμμv?vx=f′(μ)?6ec8aac122bd4f6ev6ec8aac122bd4f6e?2x

=f′(6ec8aac122bd4f6e)?6ec8aac122bd4f6e6ec8aac122bd4f6e?2x

=6ec8aac122bd4f6e

解法二:y′=[f(6ec8aac122bd4f6e)]′=f′(6ec8aac122bd4f6e)?(6ec8aac122bd4f6e)′

=f′(6ec8aac122bd4f6e)?6ec8aac122bd4f6e(x2+1)6ec8aac122bd4f6e?(x2+1)′

=f′(6ec8aac122bd4f6e)?6ec8aac122bd4f6e(x2+1) 6ec8aac122bd4f6e?2x

=6ec8aac122bd4f6ef′(6ec8aac122bd4f6e)

[例2]利用導(dǎo)數(shù)求和

(1)Sn=1+2x+3x2+…+nxn1(x≠0,nN*)

(2)Sn=C6ec8aac122bd4f6e+2C6ec8aac122bd4f6e+3C6ec8aac122bd4f6e+…+nC6ec8aac122bd4f6e,(nN*)

命題意圖:培養(yǎng)考生的思維的靈活性以及在建立知識(shí)體系中知識(shí)點(diǎn)靈活融合的能力.屬

★★★★級(jí)題目.

知識(shí)依托:通過對(duì)數(shù)列的通項(xiàng)進(jìn)行聯(lián)想,合理運(yùn)用逆向思維.由求導(dǎo)公式(xn)′=nxn1,可聯(lián)想到它們是另外一個(gè)和式的導(dǎo)數(shù).關(guān)鍵要抓住數(shù)列通項(xiàng)的形式結(jié)構(gòu).

錯(cuò)解分析:本題難點(diǎn)是考生易犯思維定勢的錯(cuò)誤,受此影響而不善于聯(lián)想.

技巧與方法:第(1)題要分x=1和x≠1討論,等式兩邊都求導(dǎo).

解:(1)當(dāng)x=1時(shí)

Sn=1+2+3+…+n=6ec8aac122bd4f6en(n+1);

當(dāng)x≠1時(shí),

x+x2+x3+…+xn=6ec8aac122bd4f6e,

兩邊都是關(guān)于x的函數(shù),求導(dǎo)得

(x+x2+x3+…+xn)′=(6ec8aac122bd4f6e)′

Sn=1+2x+3x2+…+nxn1=6ec8aac122bd4f6e

(2)∵(1+x)n=1+C6ec8aac122bd4f6ex+C6ec8aac122bd4f6ex2+…+C6ec8aac122bd4f6exn,

兩邊都是關(guān)于x的可導(dǎo)函數(shù),求導(dǎo)得

n(1+x)n1=C6ec8aac122bd4f6e+2C6ec8aac122bd4f6ex+3C6ec8aac122bd4f6ex2+…+nC6ec8aac122bd4f6exn1,

x=1得,n?2n1=C6ec8aac122bd4f6e+2C6ec8aac122bd4f6e+3C6ec8aac122bd4f6e+…+nC6ec8aac122bd4f6e,

Sn=C6ec8aac122bd4f6e+2C6ec8aac122bd4f6e+…+nC6ec8aac122bd4f6e=n?2n1?

●錦囊妙計(jì)

1.深刻理解導(dǎo)數(shù)的概念,了解用定義求簡單的導(dǎo)數(shù).

6ec8aac122bd4f6e表示函數(shù)的平均改變量,它是Δx的函數(shù),而f′(x0)表示一個(gè)數(shù)值,即f′(x)=6ec8aac122bd4f6e,知道導(dǎo)數(shù)的等價(jià)形式:6ec8aac122bd4f6e.?

2.求導(dǎo)其本質(zhì)是求極限,在求極限的過程中,力求使所求極限的結(jié)構(gòu)形式轉(zhuǎn)化為已知極限的形式,即導(dǎo)數(shù)的定義,這是順利求導(dǎo)的關(guān)鍵.

3.對(duì)于函數(shù)求導(dǎo),一般要遵循先化簡,再求導(dǎo)的基本原則,求導(dǎo)時(shí),不但要重視求導(dǎo)法則的應(yīng)用,而且要特別注意求導(dǎo)法則對(duì)求導(dǎo)的制約作用,在實(shí)施化簡時(shí),首先必須注意變換的等價(jià)性,避免不必要的運(yùn)算失誤.

4.復(fù)合函數(shù)求導(dǎo)法則,像鏈條一樣,必須一環(huán)一環(huán)套下去,而不能丟掉其中的一環(huán).必須正確分析復(fù)合函數(shù)是由哪些基本函數(shù)經(jīng)過怎樣的順序復(fù)合而成的,分清其間的復(fù)合關(guān)系.

Crime has its own cycle, a magazine reported some years ago. Police records that were studied for five years from over 2,400 cities and towns show a surprising _41_ between changes in the season and crime patterns.

The pattern of crime has varied very little over a long period of years. Murder _42_ its high during July and August, as do rape and other __43__ attacks. Murder, __44__, is more than seasonal: it is a weekend crime. It is also a high time crime: 62 percent of murders are __45__ between 6 pm and 6 am.

Unlike the summer high in crimes of bodily harm, burglary has a(n) __46__ cycle. You are most __47__ to be robbed between 6 p.m. and 2 a.m. __48__ a Saturday night in December, January or February. May is the most non-criminal month of all except for one strange statistics.   __49__ dog bites are reported in this month than in any other month of the year.

Apparently our intellectual seasonal cycles are __50__ different from our criminal tendencies.

V.Reading Comprehension (35%)

Directions: Read passage A, B, C and D. Each passage is followed by several questions or unfinished statements. For each of them there are four choices. Choose the one that fits best according to the information given in the passage you have just read.

(A)

Life is difficult

It is a great truth because once we truly understand and accept it, then life is no longer difficult.

      Most do not fully see this truth. Instead they are always blaming their problems and difficulties as if life should be easy. It seems to them that their difficulties represent a special kind of suffering especially forced upon them or else upon their families, their class, their race, or even their nation.

What makes life difficult is that the process of facing and solving problems is a painful one. Problems, depending on their nature, cause in us sadness or loneliness or regret or anger or fear. These are uncomfortable feelings, often as painful as any kind of physical pain. And since life causes an endless series of problems, life is always difficult and is full of pain as well as joy.

Yet it is this whole process of meeting and solving problems that life has its meaning.

Problems are the serious test that tells success from failure. When we desire to encourage the growth of the human spirit, we challenge and encourage the human ability to solve problems, just as in school we purposely set problems for our children to solve. It is through the pain of confronting and resolving problems that we learn. As Benjamin Franklin said, “Those things that hurt, instruct.” It is for this reason that wise people learn not to fear but actually to welcome problems and actually to welcome the pain of problems.                                           

 

56. From the passage, it can be inferred that ____.

A. people like to complain about their problems

B. we become stronger by facing and solving the problems of life

C. life is difficult because our problem bring us pain

D. everybody has problems

57. The writer probably used just one short sentence in the first paragraph ________.

A. make readers laugh                        B. persuade readers   

C. save space                                     D. get readers' attention

58. According to the passage, we give school children difficult problems to solve in order to ______.

A. teach them how to respect for problems

B. help them learn to deal with pain

C. encourage them to learn

D. teach them to fear the pain of solving problems

59. The saying from Benjamin Franklin “Those things that hurt, instruct” suggests that _______.

A. pain teaches us important lessons     B. we do not learn when we are in pain

C. pain cannot be avoided                   D. we do not learn from experience

(C )

A is for always getting to work on time.

B is for being extremely busy.

C is for the conscientious(勤勤懇懇的)way you do your job.

You may be all these things at the office, and more. But when it comes to getting ahead, experts say, the ABCs of business should include a P, for politics, as in office politics. Dale Carnegie suggested as much more than 90 years ago: Hard work alone doesn't ensure career advancement. You have to be able to sell yourself and your ideas, both publicly and behind the scenes. Yet, despite the obvious rewards of engaging in office politics - a better job, a raise, praise- many people are still unable or unwilling - to "play the game."

"People assume that office politics involves some manipulative(工于心計(jì)的)behavior," says Deborah Comer, an assistant professor of management at Hofstra University. "But politics derives from the word 'polite'. It can mean lobbying(疏通)and forming associations. It can mean being kind and helpful, or even trying to please your superior, and then expecting something in return."

In fact, today, experts define office politics as proper behavior used to pursue one's own self-interest in the workplace. In many cases, this involves some form of socializing within the office environment - not just in large companies, but in small workplaces as well.

"The first thing people are usually judged on is their ability to perform well on a consistent basis," says Neil P. Lewis, a management psychologist. "But if two or three candidates are up for a promotion, each of whom has reasonably similar ability, a manager is going to promote the person he or she likes best. It's simple human nature."

Yet, psychologists say, many employees and employers have trouble with the concept of politics in the office. Some people, they say, have an idealistic vision of work and what it takes to succeed. Still others associate politics with flattery, fearful that, if they speak up for themselves, they may appear to be flattering their boss for favors.

Experts suggest altering this negative picture by recognizing the need for some self-promotion.

63. To get promoted, one must not only be competent but  ___.

A. give his boss a good impression

B. honest and loyal to his company

C. get along well with his colleagues

D. avoid being too outstanding

64. Why are many people unwilling to "play the game"?

A. They believe that doing so is impractical.

B. They feel that such behavior is unprincipled.

C. They are not good at manipulating colleagues.

D. They think the effort will get them nowhere.

65. The author considers office politics to be ____.

A. unwelcome at the workplace

B. bad for interpersonal relationships

C. essential to the development of company culture

D. an important factor for personal advancement

66. It is the author's view that ____.

A. speaking up for oneself is part of human nature

B. self-promotion does not necessarily mean flattery

C. hard work contributes very little to one's promotion

D. many employees fail to recognize the need of flattery

 

(D)

Students create online university store

Want to buy brand-name cosmetics? In need of a GRE preparation book? Plan to order a bunch of flowers for your girlfriend?

No need to rush to different stores. Students at Tsinghua University can go shopping with a click of the mouse.

Liuxingxiaozhan.com, an e-commerce company set up by Tsinghua students last year, promises to give students the most convenient shopping experiences. And while most dotcom companies off-campus are struggling to make ends meet, the owners of the student company are proudly declaring a profit.

Each month, more than 1,000 transactions are done at Liuxingxiaozhan.com. The monthly sales volume has reached 30,000 yuan, according to Tang Yang, head of the campus e-commerce web.

At Tsinghua University, nearly every dormitory has computer and Internet access, making it likely that e-commerce will prosper.

Just like the name implies, Tang said friendly services and demand-oriented supply explained the profits. The pinyin--- Liuxing, frequently used in the students’ verses--- means shooting star.

“ An old story says that when a shooting star flashes across the sky, your dreams will come true if you pray to it. So if you log on Liuxingxiaozhan, your dreams will be realized,” the 23-year-old CEO said.

He really means it.

At Liuxingxiaozhan, you can propose a new item if you want it. The webmaster may supply this commodity for you. People can comment on this proposition, saying whether the online shop should offer it or not.

“In this way, we can supply according to the demand,” Tang said.

Sending flowers to your “mm” is one new item proposed by the users. “mm” are the initials for meime, the way boys address girls at Tsinghua’s BBS.

Starting just with VCD rentals in October, 1999, Liuxingxiaozhan now covers nearly all student needs, including cosmetics, books and second-hand items.

Xiang Jie, who ordered an Avon facial mask at the virtual shop, said she was satisfied with the service.

“It is quite convenient and the service is nice. I got the mark in two days,” Xiang said. Most of her classmates use these services.

The webmasters promise that every item ordered will be sent to the destination within three days. And they pay by cash only when they have received the goods. Part-time workers will distribute the ordered goods.

But the current success does not mean they have been without failure.

“In the beginning, we suffered losses because the goods we offered did not sell,” Tang said. “This is also one of the reasons we buy information about consumer demand from our members.’

Money is another problem. Students don’t have a lot of money to invest in the business. Things improved when they received an initial venture capital investment of 1 million yuan.

However, Tang was faced with other problems. His parents, who expected the electronic engineering major to be an excellent engineer, did not know their son had been working in e-commerce until they saw a CCTV report about him.

Working day and night, like most Internet talents do, Tang said his academic performance was greatly affected by the business.

Even so, the young entrepreneur is still thinking of expanding his business.

“So far, the business is only confirmed to the Tsinghua community. Some universities are copying our model of e-commerce,” Tang said.

“We are thinking of co-operating with other universities in Beijing, Shanghai and Xi’an,” Tang added, in an effort to solve the distribution bottleneck of e-commerce with a kind of a community e-distribution box.

 

67. Which of the following statements is Not true?

A. Liuxingxiaozhan e-company is making profits

B. The yearly sales volume of Liuxingxiaozhan has reached 30,000 yuan

C. At Tsinghua University, nearly every dorm has computer and Internet access

D. Most off-campus e-companies can only make ends meet.

68. At The very beginning, Liuxingxiaozhan started with ___.

A. renting VCDs                         B. selling many kinds of goods

C. sending flowers                       D. developing software

69. Each year, Liuxingxiaozhan can do more than ____ transactions.

A. 10,000                     B. 3,000                C. 12,000                     D. 2,000

70. According to the article, Tang’s major in university is ____.

A. computer application               B. financial engineering

C. electronic engineering              D. e-commerce

 

Directions: Read the following text and choose the most suitable heading from A ? F for each paragraph. There is one extra heading which you do not need.

 

文本框: A. Great leaders’ messages are always simplified
B. What must a leader be able to do with his power?
C. Timing is one of the most important aspects of leadership
D. We produce our leaders.
E. What an image should a leader have?
F. Leaders are sure to use power.

 

 

 

 

 

 

 

文本框: 71.

 

Leadership is as much a question of timing as anything else. The leader must appear on the scene at a moment when people are looking for leadership, as Churchill did in 1940, as Roosevelt did in 1933, as Lenin did in 1917. And when he comes, he must offer a simple, eloquent message.

文本框: 72.

 

 

Great leaders are almost always great simplifiers, who cut through argument, debate and doubt to offer a solution everybody can understand and remember. Churchill warned the British to expect “blood, toil, tears and sweat”; Roosevelt told the Americans that “the only thing we have to fear is fear itself”; Lenin promised the war-weary Russians peace, land and bread. Straightforward but effective messages

文本框: 73.

 

 

We have an image of what a leader ought to be. We even recognize the physical signs; leaders may not necessarily be tall, but they must have bigger-than-life, commanding features -- Lyndon Baines Johnson’s nose and ear lobes, Ike’s broad grin. A trade-mark also comes in handy; Lincoln’s stovepipe hat, Kennedy’s rocking chair. We expect our leaders to stand out a little, not to be like an ordinary man. Half of President Ford’s trouble lay on the fact that, if you closed your eyes for a moment, you couldn’t remember his face, figure of clothes. A leader should have an unforgettable identity, instantly and permanently fixed in people’s minds.

 

文本框: 74.

 

A leader must know how to use power (that’s what leadership is about), but he also has to have the way of showing that he does. He has to be able to project firmness -- no physical clumsiness (笨拙) (like Ford), no rapid eye movements (like Carter).He won’t come until we’re ready for him, for the leader is like a mirror, reflecting back to us our own sense of purpose, putting into words our own dreams and hopes, transforming our needs and fears into coherent (連貫的) policies and programs.

 

文本框: 75.

 

Our strength makes him strong; our determination makes him determined; our courage makes him a hero; he is, in the final analysis, the symbol of the best in us, shaped by our own spirit and will. And when these qualities are lacking in us, we can’t produce him; and even with all our skill at image-building, we can’t fake him. He is, after all, merely the sum of us.
