## COURSE DESCRIPTION

The objectives of this course are: (1) to provide you with a firm understanding of the basic ideas of mathematical analysis; (2) to improve your proof writing skills up to a professional level; (3) to improve problem solving skills needed for the CAAM analysis qualifier exam; and (4) to improve your mathematical communication skills. The specific analysis topics covered include Real numbers, completeness, sequences and convergence, compactness, continuity, the derivative, the Riemann integral, the fundamental theorem of calculus. vector spaces, dimension, linear maps, inner products and norms. See the syllabus.

**Text Book:** *Undergraduate Analysis* by Lang

**Homeworks:**
This class has homework problems of two types: practice problems and portfolio problems. Practice problems are only graded for completion. Portfolio problems are problems that are similar to qualifier problems. They will be graded in a binary manner, taking into account the correctness, the elegance, and the exposition. Here are some examples of the quality of proofs expected. Portfolio problems can and should be revised until they are judged to be of professional quality. Two homework assignments will be pledged and will serve as simulated qualifier exams.

**Classroom participation and in-class presentations:**
Each day of class, one or two students will present a theorem from that day’s content. The classroom participation grade will be based on the sincerity of your preparation for these presentations. Please follow my comments and suggested structure for the presentations.

**Outside resources:**
You are not allowed to use the Problems and Solutions book accompanying Lang’s Undergraduate Analysis text for any of the homeworks.

**Disabilities:**
Any student with a disability needing academic accommodations is requested to speak with me as soon as possible. All discussions will remain confidential. Students should also contact Disability Support Services in the Ley Student center.
