Differential Equations and Linear Algebra – Edwards & Penney – 3rd Edition


For courses in and Algebra. Acclaimed authors Edwards and combine core topics in elementary equations with those concepts and of needed for a contemporary combined introduction to differential equations and linear algebra.

Known for its real-world applications and its blend of algebraic and geometric approaches, this text discusses mathematical modeling of real-world , with a fresh new computational and qualitative flavor evident throughout in figures, examples, , and applications.

In the Third Edition, new graphics and narrative have been added as needed—yet the proven chapter and section structure remains unchanged, so that class notes and syllabi will not require revision for the new edition.
