Although dependence and independence are properties of sets of elements, we also apply these terms to the elements themselves. For example, the elements in an independent set are called independent elements.虽然相关和无关是元素集的属性，我们也适用于这些元素本身。
例如，在一个独立设定的元素被称为独立元素。
If s is finite set, the foregoing definition agrees with that given in Chapter 8 for the space n V . However, the present definition is not restricted to finite sets.如果S 是有限集，同意上述定义与第8章中给出的空间n V ，然而，目前的定义不局限于有限集。
If a subset T of a set S is dependent, then S itself is dependent. This is logically equivalent to the statement that every subset of an independent set is independent.如果集合S 的子集T 是相关的，然后S 本身是相关的，这在逻辑上相当于每一个独立设置的子集是独立的语句。
If one element in S is a scalar multiple of another, then S is dependent. 如果S 中的一个元素是另一个集中的多个标量的，则S 是相关的。
If S ∈0,then S is dependent. 若S ∈0，则 S 是相关的。

Mathematical English Dr. Xiaomin Zhang Email: zhangxiaomin@§2.2 Geometry and TrigonometryTEXT A Why study geometry?Why do we study geometry? The student beginning the study of this text may well ask, “What is geometry? What can I expect to gain fro m this study?”Many leading institutions of higher learning have recognized that positive benefits can be gained by all who study this branch of mathematics. This is evident from the fact that they require study of geometry as a prerequisite to matriculation in those schools. Geometry had its origin long ago in the measurements by the Babylonians and Egyptians of their lands inundated by the floods of the Nile River. The Greek word geometry is derived from geo, meaning “earth”, and metron, meaning “measure”. As early as2000 B.C. we find the land surveyors of these people re-establishing vanishing landmarks and boundaries by utilizing the truths of geometry.Geometry is a science that deals with forms made by lines. A study of geometry is an essential part of the training of the successful engineer, scientist, architect, and draftsman. The carpenter, machinist, stonecutter, artist, and designer all apply the facts of geometry in their trades. In this course the student will learn a great deal about geometric figures such as lines, angles, triangles, circles, and designs and patterns of many kinds. One of the most important objectives derived from a study of geometry is making the student be more critical in his listening, reading, and thinking. In studying geometry he is led away from the practice of blind acceptance of statements and ideas and is taught to think clearly and critically before forming conclusions.There are many other less direct benefits the student of geometry may gain. Among these one must include training in the exact use of the English language and in the ability to analyze a new situation or problem into its basic parts, and utilizing perseverance, originality, and logical reasoning in solving the problem. An appreciation for the orderliness and beauty of geometric forms that abound in man’s works and of the creations of nature will be a byproduct of the study of geometry. The student should also develop an awareness of the contributions of mathematics and mathematicians to our culture and civilization.TEXT B Some geometrical terms1. Solids and planes.A solid is a three-dimensional figure. Common examples of solid are cube, sphere, cylinder, cone and pyramid.A cube has six faces which are smooth and flat. These faces are called plane surfaces or simply planes. A plane surface has two dimensions, length and width .The surface of a blackboard or a tabletop is an example of a plane surface.2. Lines and line segments.We are all familiar with lines, but it is difficult to define the term. A line may be represented by the mark made by moving a pencil or pen across a piece of paper. A line may be considered as having only one dimension, length. Although when we draw a line we give it breadth and thickness, we think only of the length of the trace when considering the line. A point has no length, no width, and no thickness, but marks a position. We arefamiliar with such expressions as pencil point and needle point. We represent a point by a small dot and name it by a capital letter printed beside it, as “point A” in Fig. 2-2-1.The line is named by labeling two points on it with capital letters or one small letter near it. The straight line in Fig. 2-2-2 is read “line AB” or “line l”. A straight line extends infinitely far in two directions and has no ends. The part of the line between two points on the line is termed a line segment. A line segment is named by the two end points. Thus, in Fig. 2-2-2, we refer to AB as line segment of line l. When no confusion may result, the expression “line segment AB” is often replace d by segment AB or, simply, line A B.There are three kinds of lines: the straight line, the broken line, and the curved line. A curved line or, simply, curve is line no part of which is straight. A broken line is composed of joined, straightline segments, as ABCDE of Fig. 2-2-3.3. Parts of a circle.A circle is a closed curve lying in one plane, all points of which are equidistant from a fixed point called the center (Fig. 2-2-4). The symbol for a circle is ⊙. In Fig. 2-2-4, O is the center of ⊙ABC, or simply of ⊙O. A line segment drawn from the center of the circle to a point on the circle is a radius (plural, radii) of the circle. OA, OB, and OC are radii of ⊙O, A diameter of a circle is a line segment through the center of the circle with endpoints on the circle. A diameter is equal to two radii.A chord is any line segment joining two points on the circle. ED is a chord of the circle in Fig. 2-2-4.From this definition is should be apparent that a diameter is a chord. Any part of a circle is an arc, such as arc AE. Points A and E divide the circle into minor arc AE and major arc ABE. A diameter divides a circle into two arcs termed semicircles, such as AB. Thecircumference is the length of a circle.SUPPLEMENT A Ruler-and-compass constructionsA number of ancient problems in geometry involve the construction of lengths or angles using only an idealised ruler and compass. The ruler is indeed a straightedge, and may not be marked; the compass may only be set to already constructed distances, and used to describe circular arcs.Some famous ruler-and-compass problems have been proved impossible, in several cases by the results of Galois theory. In spite of these impossibility proofs, some mathematical amateurs persist in trying to solve these problems. Many of them fail to understand that many of these problems are trivially soluble provided that other geometric transformations are allowed: for example, squaring the circle is possible using geometric constructions, but not possible using ruler and compasses alone. Mathematician Underwood Dudley has made a sideline of collecting false ruler-and-compass proofs, as well as other work by mathematical cranks, and has collected them into several books.Squaring the circle The most famous of these problems, “squaring the circle”, involves constructing a square with the same area as a given circle using only ruler and compasses. Squaring the circle has been proved impossible, as it involves generating a transcendental ratio, namely 1:√π.Only algebraic ratios can be constructed with ruler and compasses alone. The phrase “squaring the circle” is often used to mean “doing the impossible”for this reason.Without the constraint of requiring solution by ruler and compasses alone, the problem is easily soluble by a wide variety of geometric and algebraic means, and has been solved many times in antiquity.Doubling the cube Using only ruler and compasses, construct the side of a cube that has twice the volume of a cube with a given side. This is impossible because the cube root of 2, though algebraic, cannot be computed from integers by addition, subtraction, multiplication, division, and taking square roots.Angle trisection Using only ruler and compasses, construct an angle that is one-third of a given arbitrary angle. This requires taking the cube root of an arbitrary complex number with absolute value 1 and is likewise impossible.Constructing with only ruler or only compassIt is possible, as shown by Georg Mohr, to construct anything with just a compass that can be constructed with ruler and compass. It is impossible to take a square root with just a ruler, so some things cannot be constructed with a ruler that can be constructed with a compass; but given a circle and its center, they can be constructed.Problem How can you determine the midpoint of any given line segment with only compass?SUPPLEMENT B Archimedes and On the Sphere and the CylinderArchimedes(287 BC-212 BC) was an Ancient mathematician, astronomer, philosopher, physicist and engineer born in the Greek seaport colony of Syracuse. He is considered by some math historians to be one of history's greatest mathematicians, along with possibly Newton, Gauss and Euler.He was an aristocrat, the son of an astronomer, but little is known of his early life except that he studied under followers of Euclid in Alexandria, Egypt before returning to his native Syracuse, then an independent Greek city-state. Several of his books were preserved by the Greeks and Arabs into the Middle Ages, and, fortunately, the Roman historian Plutarch described a few episodes from his life. In many areas of mathematics as well as in hydrostatics and statics, his work and results were not surpassed for over 1500 years!He approximated the area of circles (and the value of ¼) by summing the areas of inscribed and circumscribed rectang les, and generalized this "method of exhaustion," by taking smaller and smaller rectangular areas and summing them, to find the areas and even volumes of several other shapes. This anticipated the results of the calculus of Newton and Leibniz by almost 2000 years!He found the area and tangents to the curve traced by a point moving with uniform speed along a straight line which is revolving with uniform angular speed about a fixed point. This curve, described by r = a in polar coordinates, is now called the "spiral of Archimedes." With calculus it is an easy problem; without calculus it is very difficult.The king of Syracuse once asked Archimedes to find a way of determining if one of his crowns was pure gold without destroying the crown in the process. The crown weighed the correct amount but that was not a guarantee that it was pure gold. Thestory is told that as Archimedes lowered himself into a bath he noticed that some of the water was displaced by his body and flowed over the edge of the tub. This was just the insight he needed to realize that the crown should not only weigh the right amount but should displace the same volume as an equal weight of pure gold. He was so excited by this idea that he reportedly ran naked through the streets shouting "Eureka" ("I have found it")."Give me a place to stand and I will move the earth" was his boast when he discovered the laws of levers and pulleys. Since it was impossible to challenge that statement directly, he was asked to move a ship which had required a large group of laborers to put into position. Archimedes did so easily by using a compound pulley system.During the war between Rome and Carthage, the Roman fleet decided to attack Syracuse, but Archimedes had been at work devising a few surprises. There were catapults with adjustable ranges which could throw objects which weighted over 500 pounds. The ships which survived the catapults were met with poles which reached over the city walls and dropped heavy stones onto the ships. Large grappling hooks attached to levers lifted the ships out of the water and then dropped them. During another failed assault, it is said that Archimedes had the soldiers of Syracuse use specially shaped and shined shields to focus the sunlight onto the sails to set them afire. This was more than the terrified sailors could stand, and the fleet withdrew. Unfortunately, the city began celebrating a bit early, and Marcellus captured Syracuse by attackingfrom the landward side during the celebration. "Archimedes, who was then, as fate would have it, intent upon working out some problem by a diagram, and having fixed his mind alike and his eyes upon the subject of his speculation, he never noticed the incursion of the Romans, nor that the city was taken. In this transport of study and contemplation, a soldier, unexpectedly coming upon him, commanded him to follow to Marcellus, which he declined to do before he had worked out his problem to a demonstration; the soldier, enraged, drew his sword and ran him through." (Plutarch)Archimedes requested that his tombstone be decorated with a sphere contained in the smallest possible cylinder and inscribed with the ratio of the cylinder's volume to that of the sphere. Archimedes considered the discovery of this ratio the greatest of all his accomplishments.Archimedes Discovers the Volume of a SphereArchimedes balanced a cylinder, a sphere, and a cone. All of the following dimensions shown in blue are equal.Archimedes imagined taking a circular slice out of all three solids.He then imagined hanging the cylinder and the sphere from point A and suspending the solids at point F (the fulcrum).By the law of the lever Archimedes showed that2r ⨯ (cone volume + sphere volume) = 4r ⨯ (cylinder volumes)Since cylinder volume = base ⨯ height = πr2⨯2r = 2πr3and cone volume = 1/3base ⨯ height = 1/3[π⨯ (2r)2] ⨯ (2r) = 8/3πr3so sphere volume = 2 cylinder volumes - cone volume = 4/3πr3Problem 1 Can you obtain the volume of a cone by the same argument above?Problem 2 (about π) Among the earliest Chinese circle-squarers mention must be made of Chang Hung in the first place. Chang’s calculation of the circle, however, has been lost, although his value of π is given in commentary on Arithmetic in Nine Sections in the form that the ratio of the square of the circular circumference to that of the perimeter of the circumscribed squareis 5 to 8. This is equivalent to taking π at ____.。

微分方程起源于17世纪，当时牛顿，莱布尼茨，伯努 利家族解决了一些来自几何和力学的简单的微分方程。
These early discoveries, beginning about 1690, gradually led to the development of a lot of “special tricks” for solving certain special kinds of differential equation. 开始于1690年的早期发现，逐渐导致了解某些特殊类 型的微分方程的大量特殊技巧的发展。
另一方面，如下方程是偏微分方程的一个例子。

10-C Applications of matrices
In recent years the applications of matrices in mathematics and in many diverse fields have increased with remarkable speed. Matrix theory plays a central role in modern physics in the study of quantum mechanics. 近年来，在数学和许多各种不同的领域中，矩阵的应 用一直以惊人的速度不断增加。在研究量子力学时， 矩阵理论在现代物理学上起着主要的作用。
Or a radioactive substance may be disintegrating at a known rate and we may be required to determine the amount of material present after a given time.
我们马上就会发现(9.1)的每一个解都一定是f(x)=Cex 这种形式，这里C可以是任何常数。
On the other hand, an equation like
2 f ( x, y) 2 f ( x, y) 0 2 2 x y
is an example of a partial differential equation.
Requirements:
1. 理解微分方程的分类。
2. 理解矩阵学习的重要性。
9-A Introduction
A large variety of scientific problems arise in which one tries to determine something from its rate of change. 大量的科学问题需要人们根据事物的变化率来确定该 事物。 For example , we could try to compute the position of a moving particle from a knowledge of its velocity or acceleration. 例如，我们可以由已知速度或者加速度来计算移动质 点的位臵.
These equations are called differential equations, and their study forms one of the most challenging branches of mathematics. 这些方程称为微分方程，对其研究形成了数学中最具 有挑战性的一个分支。 Differential equations are classified under two main headings: ordinary and partial, depending on whether the unknown is a function of just one variable or of two more variables. 微分方程根据未知量是单变量函数还是多变量函数分 成两个主题：常微分方程和偏微分方程。
Matrix methods are used to solve problems in applied differential equations, specifically, in the area of aerodynamics, stress and structure analysis. One of the most powerful mathematical methods for psychological studies is factor analysis, a subject that makes wide use of matrix methods. 解决应用微分方程，特别是在空气动力学，应力和结 构分析中的问题，要用矩阵方法。心理学研究上一种 最强有力的数学方法是因子分析，这也广泛的使用矩 阵(方)法 .
The study of differential equations is one part of mathematics that, perhaps more than any other, has been directly inspired by mechanics, astronomy, and mathematical physics. 微分方程的研究是数学的一部分，也许比其他分支更 多的直接受到力学，天文学和数学物理的推动。 Its history began in the 17th century when Newton, Leibniz, and the Bernoullis solved some simple differential equations arising from problems in geometry and mechanics.
No matter what the students’ field of major interest is , knowledge of the rudiments of matrices is likely to broaden the range of literature that he can read with understanding .
Recent developments in mathematical economics and in problems of business administration have led to extensive use of matrix methods. The biological sciences, and in particular genetics, use matrix techniques to good advantage. 近年来，在数量经济学和企业管理问题方面的发展 已经导致广泛的使用矩阵法。生物科学，特别在遗 传学方面，用矩阵的技术很有成效。
尽管这些特殊的技巧只是适用于相对较少的几种情况， 但他们能够解决许多出现于力学和几何中的微分方程， 因此，他们的研究具有重要的实际应用。
Some of these special methods and some of the problems which they help us solve are discussed near the end of this chapter. 这些特殊的技巧和利用这些技巧可以解决的一些问题 将在本章最后讨论。
Although these special tricks are applicable in relatively few cases, they do enable us to solve many differential equations that arise in mechanics and geometry, so their study is of practical importance.
又如，某种放射性物质可能正在以已知的速度进行衰 变，需要我们确定在给定的时间后遗留物质的总量。
※In examples like these, we are trying to determine an unknown function from prescribed information expressed in the form of an equation involving at least one of the derivatives of the unknown function . 在类似的例子中，我们力求由方程的形式表述的信息 来确定未知函数，而这种方程至少包含了未知函数的 一个导数。
A simple example of an ordinary differential equation is the relation f'(x)=f(x) (9.1) which is satisfied, in particular by the exponential function, f(x)=ex . 常微分方程的一个简单例子是f'(x)=f(x) ，特别地， 指数函数f(x)=ex 满足这个等式。 We shall see presently that every solution of (9.1) must be of the form f(x)=Cex , where C may be any constant.
不管学生主要兴趣是什么，矩阵基本原理的知识都 可能扩大他能读懂的文献的范围。 The solution of n simultaneous linear equations in n unknowns is one of the important problems of applied mathematics. 解一有n个未知数的n个联立（线性）方程组是应用 数学的一个重要问题。
