Preface
This book is a result of feedback from many readers of the book Engineering with
Mathcad: Using Mathcad to Create and Organize your Engineering Calculations.
The goal of Engineering with Mathcad was to get readers using Mathcad’s tools
as quickly as possible. This was accomplished by providing a step-by-step
approach that enabled easy learning. As a result of reader feedback, Essential
Mathcad makes it even easier to learn Mathcad. We added a new Chapter 1 that
quickly introduces many useful Mathcad concepts. By the end of Chapter 1 you
should be able to create and edit Mathcad expressions, use the Mathcad toolbars
to access important features, understand the difference between the various
equal signs, understand math and text regions, know how to create a user-defined
function, attach and display units, create arrays, understand the difference
between literal subscripts and array subscripts, use range variables, and plot an
X-Y graph. Readers felt that the discussion of Mathcad settings and templates in
Part 1 slowed down their learning of Mathcad. As a result of this feedback, the
chapters Mathcad Settings, Customizing Mathcad, and Templates have been
moved to Part IV. These chapters will have more meaning after readers have a
greater understanding of Mathcad. Most of the material from Engineering with
Mathcad is included in this book, but it has been rearranged in order to allow
quicker access to Mathcad’s tools.
Readers asked for more applied examples of using Mathcad from various disci-
plines. Essential Mathcad provides many additional examples from fields such as:
Chemistry, water resources, hydrology, engineering mechanics, sanitary engineer-
ing, and taxes. These examples help illustrate the concepts covered in each chapter.
A challenge with any book is to hit a balance between too little material and too
much material. Based on feedback from Engineering with Mathcad, I feel that
we have achieved a good balance in Essential Mathcad. Some have said that
the first edition did not cover enough advanced topics for their math, physics
or advanced engineering courses. Others asked for coverage of some essential
engineering topics. On the other hand, some said that the book was too long
and covered too much material. Essential Mathcad is an attempt to achieve an
even better balance. By adding the new Chapter 1, An Introduction to Mathcad,
and rearranging other chapters, I think we have helped make learning Mathcad
even easier. By adding discussion of some requested topics, I think we have satis-
fied the desires of many readers who wanted discussion of more topics. This
book cannot and does not include a discussion of all the many Mathcad functions
and features. It does attempt to focus on the functions and features that will be
most useful to a majority of the readers.

BOOK OVERVIEW
This book uses an analogy of teaching you how to build a house. If you were to
learn how to build a house, the final goal would be the completed house.
Learning how to use the tools would be a necessary step, but the tools are just
a means to help you complete the house. It is the same with this book. The ulti-
mate goal is to teach you how to apply Mathcad to build comprehensive project
calculations.
In order to begin building, you need to learn a little about the tools. You also need
to have a toolbox where you can put the tools. When building a house, there are
simple hand tools and more powerful power tools. It is the same with Mathcad.
We will learn to use the simple tools before learning about the power tools. After
learning about the tools, we learn to build.
This book is divided into four parts:
Part I—Building Your Mathcad Toolbox. This is where you build your Mathcad
toolbox—your basic understanding of Mathcad. It teaches the basics of the Math-
cad program. The chapters in this part create a solid foundation upon which to
build.
Part II—Hand Tools for Your Mathcad Toolbox. The chapters in this part will
focus on simple features to get you comfortable with Mathcad.
Part III—Power Tools for you Mathcad Toolbox. This part addresses more com-
plex and powerful Mathcad features.
Part IV—Creating and Organizing Your Project Calculations with Mathcad. This is
where you start using the tools in your toolbox to build something—project cal-
culations. This part discusses embedding other programs into Mathcad. It also dis-
cusses how to assemble calculations from multiple Mathcad files, and files from
other programs.
ADDITIONAL RESOURCES
This book is written as a supplement to the Mathcad Help and the Mathcad User’s
Guide. It adds insights not contained in these resources. You should become
familiar with the use of both of these resources prior to beginning an earnest
study of this book.

ccess Mathcad Help, click
Mathcad Help
from the
Help
menu, or press the
F1
key. The Mathcad User’s Guide is a PDF file located in the
Mathcad program directory in the “doc” folder.
Preface xxi
In addition to the Mathcad Help and the Mathcad User’s Guide, the Mathcad
Tutorials provide an excellent resource to help learn Mathcad. The Mathcad
Tutorials are accessed by clicking
Tutorials
from the
Help
menu. Take the oppor-
tunity to review some of the topics covered by the tutorials.
This book (if sold in North America) includes a CD containing the full, non-
expiring version of Mathcad v.14. The software is intended for educational use
only. The book along with CD provides a complete introduction to learning and
using Mathcad. A companion website is provided along with the text and
includes links to additional exercises and applications, errata, and other updates
related to the book. Please visit

TEMINOLOGY
There are a few terms we need to discuss in order to communicate effectively.
The terms, “click,” “clicking” or “select” will mean to click with the left mouse
button.
The terms “expression” and “equation” are sometimes used interchangeably. “The
term “equation” is a subset of the term “expression.” When we use the term
“equation,” it generally means some type of algebraic math equation that is being
defined on the right side of the definition symbol “:=”. The term “expression” is
broader. It usually means anything located to the right of the definition symbol.
It can mean “equation” or it can mean a Mathcad program, a user-defined func-
tion, a matrix or vector or any number of other Mathcad elements.
