Textbook in PDF format

Introductory Differential Equations, Sixth Edition provides accessible explanations and many robust sample problems. This valuable resource is appropriate for a first semester course in introductory ordinary differential equations (including Laplace transforms); for a second course in Fourier series and boundary value problems; and for students with no background on the subject. The book provides the foundations to assist students in learning not only how to read and understand differential equations, but also how to read technical material in more advanced texts as they progress through their studies
