Elementary Differential Equations and Boundary Value Problems, 9th Edition

October 2008, ©2009
Elementary Differential Equations and Boundary Value Problems, 9th Edition (EHEP000254) cover image
The new 9th edition of Elementary Differential Equations and Boundary Value Problems, like its predecessors, is written from the viewpoint of the applied mathematician, whose interest in differential equations may sometimes be quite theoretical, sometimes intensely practical, and often somewhere in between.  The authors have sought to combine a sound and accurate (but not abstract) exposition of the elementary theory of differential equations with considerable material on methods of solution, analysis, and approximation that have proved useful in a wide variety of applications.  The 9th edition includes new problems and examples, as well as expanded explanations to help motivate students. 

The book is written primarily for undergraduate students of mathematics, science, or engineering, who typically take a course on differential equations during their first or second year of study. The main prerequisite for reading the book is a working knowledge of calculus, gained from a normal two- or three-semester course sequence or its equivalent.  Some familiarity with matrices will also be helpful in the chapters on systems of differential equations.
