This book is designed for a junior- or senior-level course. It contains a numerical analysis package and a symbolic manipulator to aid in the application of the basic tools of mathematics to the formulation and solution of problems in fluid dynamics, solid mechanics, electromagnetism, and other fields. Mathematica and MATLAB are used throughout the text in examples and projects. The standard Table of Contents and familiar level of difficulty are augmented by Mathematica and MATLAB, which are used the way practicing engineers use them.
