Second course in ordinary differential equations for scientists and engineers

This book fills the need for a junior-senior level book on the more advanced topics of differential equations. It attempts to blend mathematical theory with nontrivial applications from various disciplines. It does not contain lengthy proofs of mathematical theorems. In each case, examples are shown to support theorems and their practical use, and in some cases an "intuitive proof" is included. A wide range of topics is included to afford flexibility if used for a course.
