Real Analysis via Sequences and Series, Softcover reprint of the original 1st ed. 2015 Undergraduate Texts in Mathematics Series

This text gives a rigorous treatment of the foundations of calculus. In contrast to more traditional approaches, infinite sequences and series are placed at the forefront. The approach taken has not only the merit of simplicity, but students are well placed to understand and appreciate more sophisticated concepts in advanced mathematics. The authors mitigate potential difficulties in mastering the material by motivating definitions, results and proofs. Simple examples are provided to illustrate new material and exercises are included at the end of most sections. Noteworthy topics include: an extensive discussion of convergence tests for infinite series, Wallis?s formula and Stirling?s formula, proofs of the irrationality of ? and e and a treatment of Newton?s method as a special instance of finding fixed points of iterated functions.

Concepts such as continuity, differentiation and integration, are approached via sequences

Contains carefully selected, clearly explained examples and counterexamples to help the reader understand and apply concepts

Approach taken has simplicial merit and places students in a position to understand more sophisticated concepts that play central in more advanced fields
