Description
Free Mathematica 10 Update Included! Now available from www.wiley.com/go/magrab
Updated material includes:
 Creating regions and volumes of arbitrary shape and determining their properties: arc length, area, centroid, and area moment of inertia
 Performing integrations, solving equations, and determining the maximum and minimum values over regions of arbitrary shape
 Solving numerically a class of linear second order partial differential equations in regions of arbitrary shape using finite elements
An Engineer's Guide to Mathematica enables the reader to attain the skills to create Mathematica 9 programs that solve a wide range of engineering problems and that display the results with annotated graphics. This book can be used to learn Mathematica, as a companion to engineering texts, and also as a reference for obtaining numerical and symbolic solutions to a wide range of engineering topics. The material is presented in an engineering context and the creation of interactive graphics is emphasized.
The first part of the book introduces Mathematica's syntax and commands useful in solving engineering problems. Tables are used extensively to illustrate families of commands and the effects that different options have on their output. From these tables, one can easily determine which options will satisfy one's current needs. The order of the material is introduced so that the engineering applicability of the examples increases as one progresses through the chapters. The second part of the book obtains solutions to representative classes of problems in a wide range of engineering specialties. Here, the majority of the solutions are presented as interactive graphics so that the results can be explored parametrically.
Key features:
 Material is based on Mathematica 9
 Presents over 85 examples on a wide range of engineering topics, including vibrations, controls, fluids, heat transfer, structures, statistics, engineering mathematics, and optimization
 Each chapter contains a summary table of the Mathematica commands used for ease of reference
 Includes a table of applications summarizing all of the engineering examples presented.
 Accompanied by a website containing Mathematica notebooks of all the numbered examples
An Engineer's Guide to Mathematica is a musthave reference for practitioners, and graduate and undergraduate students who want to learn how to solve engineering problems with Mathematica.
