Linear Algebra

Fraleigh and Beauregard's text is known for its clear presentation and writing style, mathematical appropriateness, and overall student usability. Its inclusion of calculus-related examples, true/false problems, section summaries, integrated applications, and coverage of Cn make it a superb text for the sophomore or junior-level linear algebra course. This Third Edition retains the features that have made it successful over the years, while addressing recent developments of how linear algebra is taught and learned. Key concepts are presented early on, with an emphasis on geometry.1. Vectors, Matrices, and Linear Systems. Vectors in Euclidean Spaces. The Norm and the Dot Product. Matrices and Their Algebra. Solving Systems of Linear Equations. Inverses of Square Matrices. Homogeneous Systems, Subspaces, and Bases. Application to Population Distribution (Optional). Application to Binary Linear Codes (Optional). 2. Dimension, Rank, and Linear Transformations. Independence and Dimension. The Rank of a Matrix. Linear Transformations of Euclidean Spaces. Linear Transformations of the Plane (Optional). Lines, Planes, and Other Flats (Optional). 3. Vector Spaces. Vector Spaces. Basic Concepts of Vector Spaces. Coordinatization of Vectors.
