This text takes a strong mathematical modeling approach. By integrating modeling throughout the text, the authors provide a better intuitive understanding of the concepts presented. They also take what students learned in calculus and apply it to real-world problems. The text is loaded with relevant applications, many of which are engineering-oriented. The text includes coverage of phase-plane analysis and control systems.Giordano, Frank R. is the author of 'Differential Equations A Modeling Approach' with ISBN 9780201172089 and ISBN 0201172089.
