Page 12 - Calculus Demystified

PREFACE

Calculus is one of the milestones of Western thought. Building on ideas of
Archimedes, Fermat, Newton, Leibniz, Cauchy, and many others, the calculus is
arguably the cornerstone of modern science. Any well-educated person should
at least be acquainted with the ideas of calculus, and a scientifically literate person
must know calculus solidly.
Calculus has two main aspects: differential calculus and integral calculus.
Differential calculus concerns itself with rates of change. Various types of change,
both mathematical and physical, are described by a mathematical quantity called
the derivative. Integral calculus is concerned with a generalized type of addition,
or amalgamation, of quantities. Many kinds of summation, both mathematical and
physical, are described by a mathematical quantity called the integral.
What makes the subject of calculus truly powerful and seminal is the Funda-
mental Theorem of Calculus, which shows how an integral may be calculated by
using the theory of the derivative. The Fundamental Theorem enables a number
of important conceptual breakthroughs and calculational techniques. It makes the
subject of differential equations possible (in the sense that it gives us ways to solve
these equations).
Calculus Demystified explains this panorama of ideas in a step-by-step and acces-
sible manner. The author, a renowned teacher and expositor, has a strong sense of
the level of the students who will read this book, their backgrounds and their
strengths, and can present the material in accessible morsels that the student can
study on his own. Well-chosen examples and cognate exercises will reinforce the
ideas being presented. Frequent review, assessment, and application of the ideas
will help students to retain and to internalize all the important concepts of calculus.
We envision a book that will give the student a firm grounding in calculus.
The student who has mastered this book will be able to go on to study physics,
engineering, chemistry, computational biology, computer science, and other basic
scientific areas that use calculus.
Calculus Demystified will be a valuable addition to the self-help literature.
Written by an accomplished and experienced teacher (the author of How to Teach
Mathematics), this book will aid the student who is working without a teacher.
