"Functions for Real Variables" by E. J. Townsend is a foundational exploration of the principles governing the calculus and analysis of real functions. Written during a transformative period in mathematical education, this work provides a rigorous introduction to the fundamental concepts of real analysis, including the properties of sets of points, the theory of limits, and the continuity and differentiability of functions.

The text systematically develops the logic behind the real number system, offering clear explanations and proofs that remain relevant for students and scholars of mathematics. Townsend's approach emphasizes clarity and logical progression, making complex topics such as infinite series and the Riemann integral accessible. This book serves as an essential resource for those seeking a deep understanding of the mathematical structures that underpin modern calculus.

As a classic text in the field, "Functions for Real Variables" highlights the evolution of mathematical thought in the early 20th century. Its structured presentation of theorems and mathematical rigor makes it a valuable reference for anyone interested in the history of mathematics or the formal development of real variable theory.

Store Description

We first started out as ?The Paperback Exchange,? a chain of physical bookstores where we would part exchange your beloved books for new stories to transport you to faraway places. However, as shopping started to evolve to online shops and marketplaces, we bid our stores goodbye to become ?PBShop.? This transition has only allowed us to blossom as we now ship thousands of titles to book lovers across the globe. We pride ourselves in being a community of local book lovers which allows our passion and devotion to shine in everything we do. In 2020 we not only celebrated our 20th birthday but our 1st birthday as being completely employee owned after becoming an E.O.T in September 2019. We are proud to be different and embrace standing apart on a book mountain by working from a virtual inventory which allows us to provide thousands of books that may be difficult to get for your bookshelf or your studies. Working with a number of different suppliers allows us to explore other avenues such as puzzles, sheet music and even stationery so we really do have something for everyone. Life is about being versatile in all realms of existence. If this is your first visit or you are a returning customer, we would like to welcome you to the PBShop family, for there is no friend as loyal as a book. We are a company who put our customers at the centre of everything we do as we understand the importance of reading because once you learn to read, you will forever be free. There are a whole lot of things in this world of ours that we are yet to explore, which is why we will forever inspire curious minds.
