This example-rich reference fosters a smooth transition from elementary ordinary differential equations to more advanced concepts. Asmar's relaxed style and emphasis on applications make the material accessible even to readers with limited exposure to topics beyond calculus.Encourages computer for illustrating results and applications, but is also suitable for use without computer access. Contains more engineering and physics applications, and more mathematical proofs and theory of partial differential equations, than the first edition. Offers a large number of exercises per section. Provides marginal comments and remarks throughout with insightful remarks, keys to following the material, and formulas recalled for the reader's convenience. Offers Mathematica files available for download from the author's website.A useful reference for engineers or anyone who needs to brush up on partial differential equations.Asmar, Nakhle H. is the author of 'Partial Differential Equations with Fourier Series and Boundary Value Problems (2nd Edition)', published 2004 under ISBN 9780131480964 and ISBN 0131480960.
