This introductory differential equations textbook presents a convenient way for professors to integrate symbolic computing into the study of differential equations and linear algebra. Mathematica provides the necessary computational power and is employed from the very beginning of the text. Each new idea is interactively developed using it.

After first learning about the fundamentals of differential equations and linear algebra, the student is immediately given an opportunity to examine each new concept using Mathematica. All ideas are explored utilizing Mathematica, and though the computer eases the computational burden, the student is encouraged to think about what the computations reveal, how they are consistent with the mathematics, what any conclusions mean, and how they may be applied.

This new edition updates the text to Mathematica 5.0 and offers a more extensive treatment of linear algebra. It has been thoroughly revised and corrected throughout.

It has been said that what is wrong with the world is that we use people and love things instead of the other way around. Well, what if things were using people? That question is answered within these pages. Here, we have fifteen authors who have probed their deepest fears to transport you into a world where the enemy has no face. It could be a phone, a book, a calendar or even a pair of shoes. When ordinary objects become something to fear, where can you ever be safe? We have met the enemy and it is our Possessions The Phone by Clay Cross The Doorbell by John Reti Bullet by Anthony Calhoun Timer by Abbey Sweeny Good Luck by Scott Lefebvre Victory Assured by C. L.
