Real Analysis – mth440 (3 credits)

This course focuses on the functions of real variables. Students investigate the topology of the real line and plane, and use these concepts to prove limit and convergence theorems about sequences, series, and functions. Students also examine continuity, differentiation, and the Riemann integral.

This undergraduate-level course is 5 weeks. This course is available to take individually or as part of a degree or certificate program. To enroll, speak with an Enrollment Representative.
