CATALOG DESCRIPTION:

Math 01.330  Introduction to Real Analysis I                                                                             3 s.h.
(Prerequisites: Math 01.230 Calculus III or the equivalent)

This course prepares the student for more advanced courses in analysis as well as introducing rigorous mathematical thought processes.  Topics included are: sets, functions, the real number system, sequences, limits, continuity and derivatives.

OBJECTIVES:

Students will demonstrate the ability to use rigorous mathematical thought processes in the following areas: sets, functions, sequences, limits, continuity, and derivatives.
