山西省2013专升本 高等代数 证明题
山西省2013专升本高等代数证明题高等代数作为数学领域的重要分支,对于专升本的考生来说是具有一定挑战性的。
在 2013 年山西省专升本考试中,高等代数的证明题更是对考生的知识掌握和逻辑思维能力进行了深入的考查。
高等代数中的证明题通常需要考生对基本概念、定理和性质有深刻的理解,并能够熟练运用各种数学方法和技巧进行推理和论证。
在面对这些证明题时,考生首先要有清晰的思路,明确题目所涉及的知识点和需要证明的结论。
比如说,有这样一道证明题:证明若一个 n 阶矩阵 A 满足 A²= A ,则 A 可对角化。
这道题就需要我们从矩阵可对角化的定义和性质出发进行思考。
我们知道,一个矩阵可对角化的充要条件是它有 n 个线性无关的特征向量。
那么对于 A²= A 这个条件,我们可以先考虑它的特征值。
设λ 是A 的特征值,x 是对应的特征向量,那么有 Ax =λx 。
将 A²= A 两边同时乘以 x ,得到 A²x = Ax ,即λ²x =λx ,从而得到λ² λ = 0 ,解得λ = 0 或λ = 1 。
接下来,我们要证明 A 有 n 个线性无关的特征向量。
因为 A²= A ,所以 A(A E) = 0 ,其中 E 是单位矩阵。
这意味着矩阵 A E 的列向量都是方程 Ax = 0 的解。
又因为秩(A) +秩(A E) = n ,所以矩阵 A E 的零空间的维数等于n 秩(A E) ,也就是矩阵 A 属于特征值 1 的线性无关的特征向量的个数。
同理,矩阵 A 属于特征值 0 的线性无关的特征向量的个数为 n 秩(A) 。
而秩(A) +秩(A E) = n ,所以属于特征值 0 和 1 的线性无关的特征向量的个数之和为 n ,即 A 可对角化。
再看另一道证明题:设 V 是数域 P 上的 n 维线性空间,σ 是 V 上的线性变换,证明σ 可逆当且仅当σ 是双射。

Ⅱ.Reading Comprehension(1 point×20=20 points)Directions: There are four reading passages in this part.Each passage followed by some questions or unfinished statements.For each of then there are four choices marked A,B,C and D.Write your answers on the ANSWER SHEET.1 The sale of gods and services is not restricted, to local regional or national markets;it often takes place on international basis.Nation import goods that they lack or cannot produce as efficiently as other nations, and they export goods that they can produce more efficiently.This exchange of goods and services in the world, or global market is known as international trade.There are there main benefits to be gained form this type of exchange.First, international trade marks scarce goods availableto nations that need or desire them.When a nation lacks the resources needed to produce goods domestically, it may import them form anther country.Second, international trade allows a nation to specialize in production of those goods for which it is particularly suited.This ofter results in increased output, decreased costs, and higher national standard of living.Natural, human, and technical resources help determine which products a nation will specialize in.There are two economic principles that help explain how and when specialization is advantageous.According to the theory of absolute advantage, a nation ought to specialize in the goods that it can produce more cheaply than its competitors or in the goods that no other nation is able to produce.According to the theory of comparative advantage, a nation ought to concentrate on the products that it can produce most efficiently and profitably.The third benefit of international trade is its political effects.Nations that trade together develop common interests which may help them overcome political differences.Economic cooperation has been the foundation for many political alliances.21.Nations import goods they __________.A.produce efficiently B.specialize in ck or can't produce efficiently D.do not need or desire22.Specialization often results in ___________.A.increased outputB.decreased costsC.higher standard of livingD.all of the above23.What is the best title for this passage? A.Three Benefits B.Why Nations Trade C.What is International Trade D.Two Economic Principles 24.According to the passage, if the U.S is able to specialize in the computer industry, it is due to its ___________ resources.A.natural B.technical C.human D.international 25.Here are some advantages of international trade concerning importing nations except ___________.A.A great variety of goods isavailable B.The national standard of living is raised C.The international market gets flooded D.Foreign competition endangers domestic industries 2To be good teacher, you need some of the gifts of a good actor: you must be able to hold the attention and the interest of your audience;you must be a clever speaker, with a good, strong, pleasing voice which is fully under your control;and you must be able to act what you are teaching, in order to make its meaning chlear.The fact that a good teacher has some of the gifts of a good actor doesn't mean that he will indeed be able to act well on the stage, for there are very important differences between the teacher's work and the actor's.The actor has to speak words which he has learnt by heart;he has to repeat exactly the same words each time he plays a certain part, even his movements and the ways in which he uses his voice are usually fixed beforehand.What he has to do is to make all these carefully learnt words and actions seen natural on the stage.A good teacher works in quite a different way.His audience takes an active part in his play : they ask and answer questions, they obey orders, and if they don't understand something ,they say so.The teacher therefore has to suit his act to the needs of his audience, which is his class.He can not learn his part by heart, but must invent it as he goes along.26.What is the passage about? A.How to become an ordinary teacher.B.What a good teacher should do.C.What teachers and actors could learn form each other.D.The similarities and differences between a teacher's work and an actor's.27.The world “gifts” in line 2 means____________.A.presents B.talents C.something belonging to a good actor D.the way a teacher should act in class 28.In what way is a teacher's work different form an actor's? A.The teachermust learn everything by heart.B.He knows to control his voice bettor than an actor.C.He has to deal with unexpected situations.D.He has to use more facial expressions.29.Which of the following is true? A.A teacher has no learn by heart what exactly he is going to say in class.B.A teacher cannot decide beforehand what exactly he is going to say in class.C.A teacher voice must be nicer than an actor's.D.A teacher must have a better memory than an actor.30.According to this passage, which is the best title? A.Teacher and Actors cational system C.A Good Teacher D.How to Become a Good Actor 3Albert Einstein had s great effect on science and history, greater than only a few other men have achieved.An American university president once commented that Einstein had created a new outlook, a new view of the universe.It may be some time before the average mind understand fully the identity of time and space and on but even ordinary men understand now that the universe is something larger than ever thought before.By 1914 the young Einstein had gained world fame.He accepted the offer to become a professor at the Prussian Academy of Science in Berlin.He had few duties.little teaching and unlimited opportunities for study, but soon his peace and quite were broken by the First World War.Einstein hated violence.the misery(悲惨)of war affected him deeply, and he sat unhappily in his office doing little.He lost interest in his research.Only when peace came 1918 was he able to get back to work.In the years following World War Ⅰhonors were increasingly heaped on him.He became the head of the Kaiser Whihem Institute of Theoretical Physics.In 1921 he won the Nobel prize, and he was honored in Germany until the rise of rise of Nazism when he was driven form Germany because he was a Jew.31.The main idea ofthe first paragraph is _________________.A.the time when people know Einstein B.the filling of an American collage president C.the change in human thought produced by Einstein D.the difficulty of Einstein's thought to teacher.32.according to the American university

reputation was ruined because of his work during World War I.4About the year 1900.a small, dark-haired boy named Charles Chaplin was often seen waiting outside the back entrances of Loneon theatres.He looked thin and hungry but his blue eyes were determined.He was hoping to get work in show business for he could sing and dance.His parents were music hall artists and he had been born into the life of the stage.And, although his own boyhood was painfully hard ,he know how to mark people laugh.His own father had died form drinking too much.And his mother wasn't really able to look after Charles and his elder half-brother.Sid, because she was often sick in mind and had to be sent into hospital.Even when she was home with them sheseemed to live in a different world.Her illness made the boys very sad.As young men, he and his brother traveled to American in a small company of actors and acted in various cities.One day Charles was invited to join a new company that was making film comedies(喜剧).He accepted the offer and soon because popular.By the time he was thirty, Chaplin was the greatest, best known, and best loved comedian in the world.He had formed his own film-marking

山西省2013专升本 高等代数 证明题
山西省2013专升本高等代数证明题在山西省 2013 年专升本的高等代数考试中,证明题一直是许多考生感到棘手的部分。
高等代数作为一门抽象且逻辑性极强的学科,证明题的解答往往需要我们对基本概念、定理有着深刻的理解,以及熟练的推理和运算能力。
我们先来看看一道常见的线性方程组相关的证明题。
假设给定了一个线性方程组,要求证明其解的存在性和唯一性。
要解决这类问题,首先我们需要明确线性方程组解的判定定理。
通常,我们会通过计算系数矩阵的秩与增广矩阵的秩来进行判断。
如果系数矩阵的秩等于增广矩阵的秩,且等于未知数的个数,那么方程组有唯一解;如果秩相等但小于未知数的个数,方程组有无穷多解;若秩不相等,则方程组无解。
再来看一道关于矩阵特征值和特征向量的证明题。
比如,已知矩阵A 及其特征值λ和对应的特征向量 x,要证明对于任意正整数 k,λ^k 是矩阵 A^k 的特征值,且 x 仍是 A^k 的特征向量。
这道题就需要我们熟练掌握特征值和特征向量的定义和性质。
根据定义,Ax =λx,那么A^2x = A(Ax) =A(λx) =λ(Ax) =λ^2x,通过这样的逐步推导,可以证明出对于任意正整数 k,都有 A^kx =λ^kx。
还有一类常见的证明题是关于向量空间的。
比如证明某个集合是向量空间,这就需要我们根据向量空间的定义和性质来进行判断。
向量空间需要满足加法封闭性、数乘封闭性,并且存在零向量、每个向量都有负向量等条件。
在证明过程中,我们需要对集合中的任意两个向量进行加法和数乘运算,并验证结果是否仍在集合中。
另外,多项式相关的证明题也是考试中的常客。
例如,证明两个多项式的最大公因式的存在性和唯一性。
这就需要运用到辗转相除法以及相关的定理。
通过不断地进行除法运算,最终可以得到最大公因式,从而完成证明。
在解答高等代数证明题时,清晰的思路和严谨的逻辑是至关重要的。
每一步推理都要有依据,不能凭空臆想。
同时,要善于利用已知条件,将复杂的问题逐步化简,转化为我们熟悉的形式。
