Linear Algebra and Its Applications Upplaga 3

Linear algebra is relatively easy for students during the early stages of the course, when the material is presented in a familiar, concrete setting. But when abstract concepts are introduced, students often hit a brick wall. Instructors seem to agree that certain concepts (such as linear independence, spanning, subspace, vector space, and linear transformations), are not easily understood, and require time to assimilate. Since they are fundamental to the study of linear algebra, students' understanding of these concepts is vital to their mastery of the subject. Lay introduces these concepts early in a familiar, concrete Rn setting, develops them gradually, and returns to them again and again throughout the text. Finally, when discussed in the abstract, these concepts are more accessible. - New full color design allows for clearer understanding of figures and graphically important concepts and procedures. - MyMathLab is now available, integrating the texts content with the Student Study Guide. All of the texts many electronic resources can be found on MyMathLab. - MathXL is now available for the text, allowing students to take tests and quizzes online. - An electronic test generato
