**Ordinary Differential Equations**

covering uses of and solutions to ordinary differential equations

This book aims to lead the reader through the topic of differential equations, a vital area of modern mathematics and science. It is hoped that this book will provide information about the whole area of differential equations, but for the moment it will concentrate on the simpler equations.
