LECTURES: Monday, Wednesday, Friday 2:30pm-3:20pm, in Wean Hall 4623

INSTRUCTOR: Solesne Bourguin, office hours Monday, Friday 4:00pm-5:00pm, you also can email me (bourguin@math.cmu.edu) to set up an appointment or just drop by (Wean Hall 8206).

GRADER: Yuanyuan Feng (yuanyuaf@andrew.cmu.edu) in Wean Hall 7205.

COURSE DESCRIPTION: 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.

GRADING: problem sets (25%), midterm (35%) and a final exam (40%).
