## Differential Equations: A Modeling ApproachThis 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. |
