This book presents a variety of intriguing, surprising and appealing topics and nonroutine proofs of several theorems in real function theory. It is a reference book to which one can turn for finding answers to curiosities that arise while studying or teaching analysis.

Chapter 1 is an introduction to algebraic, irrational and transcendental numbers and contains the construction of the Cantor ternary set. Chapter 2 contains functions with extraordinary properties. Chapter 3 discusses functions that are continuous at each point but differentiable at no point. Chapters 4 and 5 include the intermediate value property, periodic functions, Rolle's theorem, Taylor's theorem, points of inflexion and tangents. Chapter 6 discusses sequences and series. It includes the restricted harmonic series, rearrangements of alternating harmonic series and some number theoretic aspects. In Chapter 7, the infinite exponential \(x\) with its peculiar range of convergence is studied. Appendix I deals with some specialized topics. Exercises are included at the end of chapters and their solutions are provided in Appendix II.

This book will be useful for students and teachers alike.

"I am impressed with the extremely complete set of references. So far as I can tell, they are all referred to in sufficient detail to make the text historically very interesting. Every relevant reference that came to my mind was already there!

"Teachers of the theory of calculus will benefit by having this book on their shelves; I wish I'd had it available when I was teaching."

-- Kenneth A. Ross, for MAA Reviews
