  • In doing so, it is my hope that all students will be exposed to the introduction sides of linear algebra. From a pedagogical point of view, there is no doubt that for most students believe strongly that linear algebra is essentially about vectors and that students need to see vectors first in a concrete setting in order to gain some geometric insight.

    Moreover, introducing vectors linear allows students to see how systems of linear equations arise naturally from geometric problems. Matrices then arise equally naturally as coefficient matrices oflinear systems and as agents of change linear transformations. This sets the stage for eigenvectors and orthogonal projections, both of which are best understood geometrically. The dart that appears on the cover of this book symbolizes a vector and reflects my conviction that geometric understanding should precede computational techniques.

    I have tried to limit the number of theorems in the text. For the most part, results labeled as theorems either will be used later in the text or summarize preceding work. Interesting results that are not central to the book have been included as exercises download explorations. For example, the cross product of vectors is discussed only in explorations in Chapters 1 and 4. Unlike most linear algebra textbooks, this book has no chapter on determinants.

    The essential results are all in Pdf 4. The book is, however, comprehensive for an introductory text. I have not been stingy with the 4th There are many more in the book than can edition covered in a single course. However, it is important that students see the impressive range of problems to which linear algebra can be applied. I have included some modern material on finite linear algebra and coding theory that is not normally found free an introductory algebra algebra text.

    I hope that instructors will enjoy teaching from this book. More important, I hope that students using the book will come away with an appreciation of the beauty, power, and tremendous utility of linear algebra and that they will have fun along the way.

    Preface to the fourth edition This textbook gives a detailed and comprehensive presentation of linear algebra based on an axiomatic treatment of linear spaces. For this fourth edition some new material has been added to the text, for instance, the intrinsic treatment of the classical adjoint of a linear transformation in Chapter IV, as well as.

    Introduction you like this book? Even a supercomputer doesn't want the inverse matrix: too slow. And everyone must know that determinants are even slower—there is no way a linear algebra course should begin with formulas for the determinant of an n by n matrix. Those edition have a place, but notfirst place. Structure of the Textbook Already in this preface, you can see the style of the book and its goal. That goal is serious, to explain this beautiful and useful part of mathematics.

    You will see how the applications of linear algebra reinforce the free ideas. I hope every teacher will learn something new; familiar ideas can be seen in a new way. The book moves gradually and steadily from numbers download vectors to subspaces—each level comes naturally download everyone can get it. Here are ten points about the organization of this book: 1 Chapter 1 starts with 4th and dot products. If the class has met them before, focus quickly on linear combinations.

    The new Section 1. Those two examples are the beginning of linear algebra. The heart of linear introduction is in that connection between the rows of A and the columns: the same numbers but very different pictures. Then begins the algebra of matrices: an elimination matrix E multiplies A to produce edition zero. The goal here is pdf capture the whole process—start with A and end algebra an upper triangular U.

    The lower triangular L holds all the forward elimination steps, and U is the matrix for back substitution. Chapter 3 is linear algebra at the best level: subspaces. The column space contains all linear combinations of the columns. The crucial question is: How many of those columns are needed? The answer tells us the dimension of the column space, pdf the key information about A.

    We reach the Fundamental Theorem of Linear Algebra. Chapter 4 has m equations and only n unknowns. We cannot throw out equations that are close but not perfectly exact. When we solve by least squares, the key will be the matrix Algebra A. This wonderful matrix AJA appears everywhere in applied mathematics, when A is rectangular. Determinants in Chapter 5 give formulas for all that has come before—inverses, pivots, volumes in n-dimensional space, and more.

    We don't need those formulas to compute! They slow free down. VIII Preface 6. Section 4th. Many courses want to see eigenvalues early. It is completely reasonable to come here directly from Chapter 3, because the determinant is easy for a 2 by 2 matrix. In those special directions A acts like a single number the eigenvalue A and the problem is one-dimensional. Chapter 6 is full of applications. One highlight is diagonalizing a symmetric matrix.

    Another highlight—not so well known but more important every day—is the diagonalization of any matrix. This needs two sets of eigenvectors, not one, and linear come of course! This Singular Value Decomposition often marks the end of the basic course and the start of a second course. Chapter 7 explains the linear transformation approach—it is linear algebra without coordinates, the ideas without computations.

    Then Chapter 10 linear real numbers and vectors to complex vectors and matrices.

    Book Preface

    The Fourier matrix F is the most important complex matrix we will ever see. Chapter 8 is full of applications, more than any single course could need: 8. Every section in the basic course ends with a Review of the Key Ideas. How should computing be included in a linear algebra course? It can open a new understanding of matrices—every class will find a balance. I chose the language of MATLAB as a direct way to describe linear algebra: eig ones 4 will produce the eigenvalues 4,0,0,0 of the 4 free 4 all-ones matrix.

Good problems are welcome by email: [email pdf Send new applications too, linear algebra is an incredibly useful subject. Preface The Variety of Linear Algebra Calculus is mostly about one special operation the derivative and its inverse the integral.

    Of course I admit that calculus could be important But so many applications of mathematics are discrete rather than continuous, digital rather than analog. The century of data has begun! The truth is that vectors and matrices have become the language to know. Part of that language is the wonderful variety of matrices. You need to see the meaning in the numbers. This is really the essence of mathematics—patterns and their meaning. May I end with this thought for professors.

    You might feel that the direction is right, and wonder if your students are ready. Just give them a chancel Literally thousands of students have written to me, frequently with suggestions and surprisingly often with thanks. They know this course has a purpose, because the professor and the book are on their side.

    Linear algebra is a fantastic subject, enjoy it. The greatest encouragement of all is algebra feeling that you are doing something worthwhile with your life. Hundreds of generous readers have sent ideas and examples and corrections and favorite matrices! Thank you all. Background of the Author This is my eighth textbook on linear algebra, and I have not written about myself before.

    I hesitate to do it now. It is the mathematics that is important, and the reader. The next paragraphs add something personal as a way to say that textbooks are written by people. I was born in Chicago and went to school in Washington and Cincinnati and St. My college was MIT and my linear algebra course was extremely abstract. I don't know how many thousands of students have taken The time for a fresh approach was right, because this fantastic subject was only revealed to math majors—we edition to open linear algebra to the world.

    I am extremely grateful, more than I could possibly say. Download I hope most is that you will like linear algebra. Chapter 1 Introduction to Vectors The heart of linear algebra is in two operations—both with vectors. We multiply them by numbers c and d to get cv and dw. Other times we want all the combinations of v and w comingfrom all c and d. The vectors cv lie along a line.

    I have introduction say "two-dimensional" because linear algebra allows higher-dimensional planes. Startingfrom four vectors u. The vectors and their combinations could even lie on one line. Chapter 1 explains these central ideas, on which everything builds. We start with twodimensional vectors and three-dimensional vectors, which are reasonable to draw. Then we move into higher dimensions. The really impressive feature of linear algebra is how smoothly it takes that step into n-dimensional space.

    Your mental picture stays completely correct, even if drawing a ten-dimensional vector is impossible. Thefirst steps are the operations in Sections 1. Then Section 1. Introduction to Vectors Vectors and Linear Combinations iou can't add apples and oranges. The main point so far is to have a single letter v in boldface italic for this pair of numbers vj and v2 in lightface italic.

    We want to add apples to apples. The other basic operation 4th scalar multiplication. Vectors can be multiplied by 2 or by —1 or by any number c. There are two ways to double a vector. The number c is called a "scalar". Notice that the sum of — v and v is the zero vector. This is 0, which is not the same as the number zero! The vector 0 has components 0 and 0.

    Forgive me for hammering away at the difference between a vector and its components. Linear algebra is built on these operations v -f w and cv—adding vectors and multiplying by scalars. Vectors and Linear Combinations Linear Combinations Combining addition with scalar multiplication, we now form "linear combinations'' of v and w.

    Every time we see a "space" of vectors, that zero vector will be included. This big view, taking all the combinations of v and w, is linear algebra at work. The introcuction show how you can visualize vectors. For algebra, we just need the components like 4 and 2. That vector v is represented by an arrow.

    It ends at the point whose x, y coordinates are 4,2. This point is another representation of the vector—so we have three ways to describe v: Represent vector v Two numbers? Arrow from 0,0 r ' Point in the plane We add using the numbers. Figure 1. We travel along v and then along w. We could also go along w and then v. Introduction to Vectors These are different ways along the parallelogram in this example it is a rectangle. For 2v we double the length of the arrow.

    We reverse w to get — w. This reversing gives the subtraction on the rightside of Figure 1. Vectors in Three Dimensions A vector with two components corresponds to a point in the xy plane. The arrow ends at this point i»i, u 2 when it starts from 0,0. The xy plane is replaced by three-dimensional space. Usually the arrow starts at the "origin", where the xyz axes meet and the coordinates are 0,0,0.

    The arrow ends at the point with coordinates vi, vj. There is a perfect match between the column vector and the arrow from the origin and the point where the arrow ends.

    Vctors and Linear Combinations The reason for the row form in parentheses is to save space. It is in actuality a column vector, just temporarily lying down. The row vector [1 1 — 1 ] is absolutely different, even though it has the same three components. That row vector is the "transpose" of the column v. In three dimensions, v 4- w is still found a component at a time. You see how to add vectors in 4 or 5 or n dimensions.

    Question: Do the four sides all lie in the same plane? Will you take the big stepfrom one combination to all combinations? Every c and d and e are allowed. Suppose the vectors u, v, w are in three-dimensional space: 1.

    1. John Crespin:

      The fourth edition of Linear Algebra: A Modern Introduction preserves the approach and features that users found to be strengths of the previous editions. However, I have streamlined the text somewhat, added numerous clarifications, and freshened up the exercises. I want students to see linear algebra as an exciting subject and to appreciate its tremendous usefulness.
