Partial differential equations fall into several areas of mathematics:
many of the greatest advances in modern science have been based on
discovering the underlying PDE for the process in question. In this
book, the emphasis is on the practical solution of problems rather than
the theoretical background. An introductory chapter recaps the
mathematical preliminaries required and exercises with solutions are
provided. With its companion volume, Analytic Methods for Partial
Differential Equations, it provides a complete introduction to the
subject.
