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


For courses in Equations and Linear Algebra. Acclaimed authors combine core topics in elementary equations with those concepts and of elementary linear needed for a contemporary combined introduction to 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 phenomena, with a fresh new computational and qualitative flavor evident throughout in figures, examples, problems, and applications.

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