"...highly recommended...a demanding text; the exercises are excellent and challenging, and some are at the level of research problems. Applied mathematicians, engineers, and scientists will appreciate this book." G.J.F. Junevicus, Choice "If you are looking for a textbook for an introdutory course on mathematical modeling, with an emphasis on differential and difference equations and basic calculus as the only prerequisite, then give this book serious consideration. It is very well written and very well structured... overall presentation of material is excellent... an excellent reference for anyone who has an interest in mathematical modeling...The foundation that this text helps to build will easily allow the reader to move on to more advanced texts on mathematical modeling."
