There are a great deal of books on introductory analysis in print today,
many written by mathematicians of the first rank. The publication of
another such book therefore warrants a defense. I have taught analysis
for many years and have used a variety of texts during this time. These
books were of excellent quality mathematically but did not satisfy the
needs of the students I was teaching. They were written for
mathematicians but not for those who were first aspiring to attain that
status. The desire to fill this gap gave rise to the writing of this
book. This book is intended to serve as a text for an introductory
course in analysis. Its readers will most likely be mathematics,
science, or engineering majors undertaking the last quarter of their
undergraduate education. The aim of a first course in analysis is to
provide the student with a sound foundation for analysis, to familiarize
him with the kind of careful thinking used in advanced mathematics, and
to provide him with tools for further work in it. The typical student we
are dealing with has completed a three-semester calculus course and
possibly an introductory course in differential equations. He may even
have been exposed to a semester or two of modern algebra. All this time
his training has most likely been intuitive with heuristics taking the
place of proof. This may have been appropriate for that stage of his
development.
