Introduction to Differential Equations

This textbook, in its third edition, is a concise introduction to differential equations for students in science and engineering. Emphasis is placed on the methods of solution, on the constructive use of qualitative analysis, and on the interconnections between differential equations and mathematical modeling. It is written in an accessible, easy-to-read format. There are numerous worked-out examples and exercises in each section, along with a wide variety of applications. The text has also been written with affordability and flexibility in mind. The author is an applied mathematician who has written several successful undergraduate and graduate textbooks on mathematical modeling and scientific computing.

This textbook was written as an introductory course in differential equations. While often taught in mathematics departments, it is not uncommon that this topic is also found in engineering departments or other school departments. The expectation is that the students will have taken at least a year of calculus before approaching this subject.
