Ebook: Elementary Differential Equations

This text is in tended for use in a first course in ordinary differential equations following elementary calculus and is designed to meet a variety of needs. Where a minimal coverage of techniques is the objective in a one-semester, three-hour course, Chapters 1 through 6 with all the starred material omitted should serve.
At the other extreme, a serious and longer course, with some attention to fine points, may be based on the full contents of the book, including starred material. It is hoped that the book will be well suited for use in institutions where a course in differential equations is generally required, as is the case in some engineering schools.
