It is intended to expand on topics introduced in the calculus sequence and to consider them at a higher mathematical level. The material covered will include: The natural number system, the integer and rational number systems: construction, definitions and main properties.
The real number system: Field and order axioms, sups and infs, completeness, integers and rational numbers.
Real sequences: Limits, accumulation points, limsup and liminf, subsequences, monotonic sequences, Cauchy's criterion, the Bolzano-Weierstrass theorem.
Topology of the real line: Open sets, closed sets, density, compactness, the Heine-Borel theorem.
Continuity: Attainment of extrema, the intermediate value theorem, uniform continuity.
Differentiation: Chain rule, local extrema, mean-value theorems, L'Hospital's rule, Taylor's theorem.
Riemann integration: Partitions, upper and lower integrals, sufficient conditions for integrability, the fundamental theorem of calculus.
Sequences of Functions: Pointwise convergence, uniform convergence, interchanging the order of limits.
PREREQUISITES: 21-122 and 21-127.
TEXTBOOK: Our reference text will be Real Analysis and Foundations, Third Edition, by Krantz.
HOMEWORK: Every Wednesday for the next Wednesday.
