Calculus is an integral and indispensable part of every mathematics course in all universities across the world. It is generally introduced early into the course because of its importance and applicability in other branches of mathematics and other sciences and economics.
This book will be useful to every undergraduate mathematics students, including but not limited to universities in India. The topics covered in this book are also compatible with the Undergraduate Curriculum Framework (UGCF) 2022 based on the National Education Policy (NEP) 2020.
The objective of this book is to present rigorous mathematical analysis in a lucid manner supported by essential examples and illustrations. Although there are several other books on calculus, this book appears fresh owing to its simplicity in its approach and language while strictly maintaining the necessary rigorous mathematical analysis. In fact, this book is a result of many years of teaching and interactions with undergraduate students, and considering and realizing their needs and problems.
Some of the important features of this book are listed below.
-
The book covers almost all important topics of differential calculus and the theory of real functions.
-
Each topic in the book is presented elaborately to make is comprehensive.
-
The book is written in simple easy to understand language and approach.
-
Rigorousness of mathematical analysis is maintained throughout.
-
A large number of examples and problems are discussed in each topic to help students understand the concepts and their applications clearly.
-
Geometrical illustrations are included wherever necessary to enhance the understanding of the topic.
-
A large number of interesting and challenging problems are provided as exercises at the end of each chapter for the students to test their progress.
-
Answers or hints to each and every exercise problems are included at the end of the book.
-
The book adopts internationally accepted conventions and symbols for uniformity.
