Elementary Differential Equations - Tapa dura

This revised edition includes problems and examples that incorporate computer technology. Many of the problems also call for graphing solutions or statements about their behaviour. In doing this, the text clearly demonstrates why solutions are no more important than the conclusions that can be drawn from them. The book includes features such as: a sound and accurate exposition of theory with attention to methods of solution, analysis, and approximation that can be used in many applications; problems on properties of solutions which emphasize the importance of understanding the qualitative behaviour of solutions; use of technology, illustrations, and problem sets to help students develop an understanding of the material; historic footnotes that trace development of the discipline and identify some outstanding individual contributions; and the answers to most of the problems in the book. This edition contains additional features such as: more figures within the text plus problems chosen to promote a more visual understanding of differential equations; problems that explore the effect of changing parameter values; an update of the numerical methods chapter and new figures and problems.
