Elementary Differential Equations (PAPERBACK)  | Released: 2016

This clear, concise fairly easy classic text is particularly well-suited to courses that emphasize finding solutions to differential equations where applications play an important role. Many illustrative examples in each chapter help the student to understand the subject. Computer applications new to this edition. • This, classic ODE book, has been so successful because it is the clearest and easiest of all texts in this market. • This is the shortest of all the major ODE texts (it covers boundary values problems and PDEs. The brevity makes it usable in quarter schools. • Includes abundant exercises and applications. • Presents a thorough treatment of power series techniques. • Presents a classical treatment of select physical problems to show how Fourier series are utilized in the solution of these problems. • Provides an introduction to the phase plane and to different types of phase portraits.Table of Contents: Definitions; Families of Curves. 2.
