"Introductory Analysis, Second Edition" is intended for the standard course on calculus limit theories that is taken after a problem solving first course in calculus (most often by junior/senior mathematics majors). Topics studied include sequences, function limits, derivatives, integrals, series, metric spaces, and calculus in n-dimensional Euclidean space. It bases most of the various limit concepts on sequential limits, which is done first. It defines function limits by first developing the notion of continuity (with a sequential limit characterization). It contains a thorough development of the Riemann integral, improper integrals (including sections on the gamma function and the Laplace transform), and the Stieltjes integral. It presents general metric space topology in juxtaposition with Euclidean spaces to ease the transition from the concrete setting to the abstract. Containing new exercises throughout, it provides a simple definition of subsequence. It has more information on function limits and L'Hospital's Rule. It provides clearer proofs about rational numbers and the integrals of Riemann and Stieltjes, and presents an appendix lists of all mathematicians named in the text. It also gives a glossary of symbols.
