For courses in Differential Equations and Linear Algebra . Concepts, methods, and applications of elementary differential equations and linear algebra In a contemporary introduction to differential equations and linear algebra, acclaimed authors Edwards, Penney, and Calvis combine core topics in elementary differential equations with concepts and methods of elementary linear algebra. Renowned for its real-world applications, exercise sets, and blend of algebraic and geometric approaches, Differential Equations and Linear Algebra discusses mathematical modeling of real-world phenomena. The 4th Edition includes fresh new computational and quantitative flavor evident throughout in figures, examples, problems, and applications. Now available, Expanded Applications, an online companion manual containing expanded applications and programming tools.
