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 π and e and a treatment of
Newton's method as a special instance of finding fixed points of
iterated functions.
