This textbook is designed for the intermediate-level course on ordinary differential equations offered at many universities and colleges. It treats, as standard topics of such a course: existence and uniqueness theory, linear s- terns, stability theory, and introductory phase-plane analysis of autonomous second order systems. The unique feature of the book is its further inc- sion of a substantial introduction to delay differential eq- tions. Such equations are motivated by problems in control theory, physics, biology, ecology, economics, inventory c- trol, and the theory of nuclear reactors....

Why Math? is designed for a general education mathematics course. It helps develop the basic mathematical literacy now generally demanded of liberal arts students. Requiring only a little background knowledge of algebra and geometry - no more than the minimum entrance requirements at most colleges - the book emphasizes quantitative reasoning and critical thinking for real life problems.In a concrete and relevant way, using extensive motivation from everyday problems, Why Math? shows what one can do with elementary mathematics and how to do it.
