This Fifth Edition provides substantial support both for teaching and for using technology in the course. As before, the text provides a modern elementary introduction to linear algebra and a broad selection of interesting applications.

The material is accessible to students with the maturity that should come from successful completion of two semesters of college-level mathematics, usually calculus. The main goal of the text is to help students master the basic concepts and skills they will use later in their careers.

The topics here follow the recommendations of the Linear Algebra Curriculum Study Group, which were based on a careful investigation of the real needs of the students and a consensus among professionals in many disciplines that use linear algebra. We hope this course will be one of the most useful and interesting mathematics classes taken by undergraduates.

Students submit homework online for instantaneous feedback, support, and assessment. This system works particularly well for computation-based skills.

Many additional resources are also provided through the MyMathLab web site. The Fifth Edition of the text is available in an interactive electronic format. Students are encouraged to develop conjectures through experimentation and then verify that their observations are correct by examining the relevant theorems and their proofs.

The resources in the interactive version of the text give students the opportunity to play with mathematical objects and ideas much as we do with our own research. The Fifth Edition includes additional support for concept- and proof-based learning.

Conceptual Practice Problems and their solutions have been added so that most sections now have a proof- or concept-based example for students to review. Additional guidance has also been added to some of the proofs of theorems in the body of the textbook. More than 25 percent of the exercises are new or updated, especially the computational exercises.

The exercise sets remain one of the most important features of this book, and these new exercises follow the same high standard of the exercise sets from the past four editions.

Later generalizations of these concepts appear as natural extensions of familiar ideas, visualized through the geometric intuition developed in Chapter 1. A central theme is to view a matrix—vector product Ax as a linear combination of the columns of A. In Chapter 1, for instance, linear transformations provide a dynamic and graphical view of matrix—vector multiplication.

Eigenvalues and Dynamical Systems Eigenvalues appear fairly early in the text, in Chapters 5 and 7. Because this material is spread over several weeks, students have more time than usual to absorb and review these critical concepts.

Eigenvalues are motivated by and applied to discrete and continuous dynamical systems, which appear in Sections 1. These two optional sections present all the vector space concepts from Chapter 4 needed for Chapter 5.

Orthogonality and Least-Squares Problems These topics receive a more comprehensive treatment than is commonly found in beginning texts. The Linear Algebra Curriculum Study Group has emphasized the need for a substantial unit on orthogonality and least-squares problems, because orthogonality plays such an important role in computer calculations and numerical linear algebra and because inconsistent linear systems arise so often in practical work.

Some applications appear in separate sections; others are treated in examples and exercises. In addition, each chapter opens with an introductory vignette that sets the stage for some application of linear algebra and provides a motivation for developing the mathematics that follows. Later, the text returns to that application in a section near the end of the chapter. A Strong Geometric Emphasis Every major concept in the course is given a geometric interpretation, because many students learn better when they can visualize an idea.

Examples This text devotes a larger proportion of its expository material to examples than do most linear algebra texts. There are more examples than an instructor would ordinarily present in class. But because the examples are written carefully, with lots of detail, students can read them on their own.

Theorems and Proofs Important results are stated as theorems. Other useful facts are displayed in tinted boxes, for easy reference. Most of the theorems have formal proofs, written with the beginner student in mind. In a few cases, the essential calculations of a proof are exhibited in a carefully chosen example.

Practice Problems A few carefully selected Practice Problems appear just before each exercise set. Complete solutions follow the exercise set. Exercises The abundant supply of exercises ranges from routine computations to conceptual questions that require more thought. Each exercise set is carefully arranged in the same general order as the text; homework assignments are readily available when only part of a section is discussed.

A notable feature of the exercises is their numerical simplicity. The exercises concentrate on teaching understanding rather than mechanical calculations. The exercises in the Fifth Edition maintain the integrity of the exercises from previous editions, while providing fresh problems for students and instructors.

They can be answered directly from the text, and they prepare students for the conceptual problems that follow. Students appreciate these questions—after they get used to the importance of reading the text carefully. Based on class testing and discussions with students, we decided not to put the answers in the text.

Writing Exercises An ability to write coherent mathematical statements in English is essential for all students of linear algebra, not just those who may go to graduate school in mathematics.

Conceptual exercises that require a short proof usually contain hints that help a student get started. For all odd-numbered writing exercises, either a solution is included at the back of the text or a hint is provided and the solution is given in the Study Guide, described below. Computational Topics The text stresses the impact of the computer on both the development and practice of linear algebra in science and engineering. Frequent Numerical Notes draw attention to issues in computing and distinguish between theoretical concepts, such as matrix inversion, and computer implementations, such as LU factorizations.

MyMathLab contains hundreds of algorithmically generated exercises that mirror those in the textbook. This system works particularly well for supporting computation-based skills. Students are encouraged to develop conjectures. The resources in the interactive version of the text give students the opportunity to interact with mathematical objects and ideas much as we do with our own research.
