# 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.

### Continuous Functions

• Prove statements about continuous functions.
• Prove continuity using rules for combinations of continuous functions.
• Prove statements about continuous functions on intervals.
• Determine whether or not a function is uniformly continuous.
• Prove statements about monotone and inverse functions.

### Differentiation

• Determine whether or not a given function is differentiable.
• Use L'Hospital's Rules to find limits of functions.
• Use Taylor's Theorem to develop polynomial approximations to functions.
