## ABSTRACT

**Solution Techniques for Elementary Partial Differential Equations, Third Edition** remains a top choice for a standard, undergraduate-level course on partial differential equations (PDEs). Making the text even more user-friendly, this third edition covers important and widely used methods for solving PDEs.

**New to the Third Edition**

- New sections on the series expansion of more general functions, other problems of general second-order linear equations, vibrating string with other types of boundary conditions, and equilibrium temperature in an infinite strip
- Reorganized sections that make it easier for students and professors to navigate the contents
- Rearranged exercises that are now at the end of each section/subsection instead of at the end of the chapter
- New and improved exercises and worked examples
- A brief
*Mathematica*^{®}program for nearly all of the worked examples, showing students how to verify results by computer

This bestselling, highly praised textbook uses a streamlined, direct approach to develop students’ competence in solving PDEs. It offers concise, easily understood explanations and worked examples that allow students to see the techniques in action.
