Differential Equations
A Modeling Approach

May 2007 | 120 pages | SAGE Publications, Inc
Differential Equations: A Modeling Approach introduces differential equations and differential equation modeling to students and researchers in the social sciences.

Key Features:

- The text is accessibly written, so that students with minimal mathematical training can understand all of the basic concepts and techniques presented.

- The author uses social sciences examples to illustrate the relevance of differential equation modeling to readers.

- Readers can use graphical methods to produce penetrating analysis of differential equation systems.

- Linear and nonlinear model specifications are explained from a social science perspective. Most interesting differential equation models are nonlinear, and readers need to know how to specify and work with such models in the social sciences.

SAGE Research Methods is a research methods tool created to help researchers, faculty and students with their research projects. SAGE Research Methods links over 175,000 pages of SAGE’s renowned book, journal and reference content with truly advanced search and discovery tools. Researchers can explore methods concepts to help them design research projects, understand particular methods or identify a new method, conduct their research, and write up their findings. Since SAGE Research Methods focuses on methodology rather than disciplines, it can be used across the social sciences, health sciences, and more.
