This book would be useful as text for undergraduate students of all Indian universities and engineering institutes, including the Indian Institutes of Technology. Real Analysis is a CORE subject in mathematics at the college level. The prerequisite for this course is Higher Secondary level mathematics including calculus. The authors have, however, included a preliminary chapter on Set Theory to make the book as self contained as possible. In addition to discussing the “basics” of a first course, the book also contains a large number of examples to aid better student understanding of the subject.
