Number of Credits:              3     

Semester:                            2

Prerequisite(s):                    MATH 2277

 

 

Course Rationale

 

This course serves to complete the foundation in real analysis required for a major in mathematics, and is designed to prepare students for advanced courses in analysis and functional analysis. It will also serve as a useful platform for further study in complex analysis, topology, dynamical systems, quantum mechanics, and mathematical statistics. The rigorous treatment of the subject (in terms of theory and examples) will provide students with an opportunity to enhance their capacity for mathematical reasoning and intuition.

 

Course Description

 

This is the follow-up course for MATH 2XXX Introduction to Real Analysis I. The course exposes students to rigorous mathematical definitions, proofs and classical results on differentiation, Riemann integration, sequences and series of functions. Major emphasis is placed on the proper use of definitions for the rigorous proof of theorems.  The following topics will be covered: Differentiation, Riemann integration, sequences and series of functions and metric spaces.

Assessment is designed to encourage students to work continuously with the course materials. Active learning will be achieved through weekly problem sheets, allowing continuous feedback and guidance on problem solving techniques in tutorials and lectures, and periodic marked assignments. Assessment will be based on the marked assignments and in-course tests followed by a final examination based on the whole course

 

Learning Outcomes

 

By the end of the course, students will be able to:

  • Provide and utilize the concept of the derivative, L'Hôpital's rule, Taylor’s formula.
  • Define and expound upon the following concepts: Upper sum, lower sum, Riemann integrability.
  • Prove the major theorems of analysis of the real line
  • Prove that certain sequences of functions converge uniformly.
  • Prove that various sequences are convergent and/or Cauchy in a metric space.
  • Prove theorems regarding compactness and connectedness in a metric space.
  • Construct counter-examples to show to show that certain hypotheses for classical theorems of real analysis are necessary.
  • Prove that certain functions are continuous in a metric space.

Teaching Methodology

 

Students will be exposed to the theoretical aspects of the mathematical analysis through informative lectures. Tutorials provided as needed during scheduled lecture hours will reinforce their learning and provide experience with the practical application of different type of problems.

The total estimated 39 contact hours may be accounted for as follows: 26 hours of lectures and 13 hours of tutorials. Course material, including practice problems, will be posted on myelearning.

 

 

Assessment     

 

The course assessment has three components:

                                                 

              Final exam:  2-hour written paper                       50%

              Two Midterm Exams     (15% each)                      30%

              Five Written Assignments (4% each)                   20%
