Prerequisites will be checked, and students not meeting them will be removed from the course by the end of the second week of classes. If a student believes that s/he does have the necessary background material, and is able to prove it (e.g., has a transfer credit from a different university), then s/he should submit a 'Prerequisite/Corequisite Waiver Request Form'.

The course is the rigorous introduction to Real Analysis. We start with the careful discussion of The Axiom of Completeness and proceed to the study of the basic concepts of limits, continuity, Riemann integrability, and differentiability.

Homework. The assignments should be submitted through Quercus. To submit, you can scan or take a photo of your work (or write your work electronically). Please make sure that the images are clear and easy to read before you submit them.

Assignment #1, due September 13: The assignment is based on the material you have learned in MAT102.
Please do the following exercises from the textbook: 1.2.3, 1.2.4, 1.2.5, 1.2.7, 1.2.8, 1.2.9, 1.2.10, 1.2.11, 1.2.12, 1.2.13.

Tutorials and presentations. Each student must be registered in one of the tutorials (on ROSI). The attendance of tutorials is mandatory. Based on the homework assignments, the students will be selected to present some of the homework problems at the tutorials. An unexcused absence at the tutorial on the day you are selected for the presentation will result in zero credit for the presentation.
Tutorials will begin on Friday of the second week of classes.

Quiz. There will be a one-hour in-tutorial quiz on Friday, September 28, or Monday, October 1, depending on your tutorial section. No aides are allowed for this quiz. The quiz will cover the material of the sections 1.3, 1.4, 2.2, 2.3, 2.4.
Recommended preparation (do not hand in): problems 1.3.2, 1.3.3, 1.3.6, 1.3.8, 1.4.8, 2.2.2, 2.2.4, 2.3.2, 2.3.7, 2.4.1, 2.4.6, 2.4.8.

Midterm Test. There will be a two-hour in-class midterm test on Thursday, November 8. No aides are allowed for this test. The test will cover the material of the sections 1.3, 1.4, 2.2, 2.3, 2.4, 2.5, 2.6, 2.7, 3.2, 3.3, 3.5, 4.2, 4.3, .4.4, 4.5, 5.2, 5.3.

Final exam. The final exam will be held on Wednesday, December 12, 5-8pm, at KN137. No aides are allowed for this test.

Additional office hours: Tuesday, December 11, 12 - 1. Location: DH3000 .

Grading. Grades will be based on the best eight out of ten homework assignements (10%), an in-tutorial quiz (10%), an in-lecture midterm test (25%), tutorial presentations (15%), attendance of tutorials and active participation in the discussions (5%), and Final exam (35%). I will also occasionally assign bonus problems.

Late work. No late work will be accepted. Special consideration for late assignments or missed exams must be submitted via e-mail within a week of the original due date. There will be no make-up quiz, midterm test, or final. Justifiable absences must be declared on ROSI, undocumented absences will result in zero credit.

E-mail policy.
E-mails must originate from a utoronto.ca address and contain the course code MAT337 in the subject line. Please include your full name and student number in your e-mail.

Academic Integrity.
Honesty and fairness are fundamental to the University of Toronto’s mission. Plagiarism is a form of academic fraud and is treated
very seriously. The work that you submit must be your own and cannot contain anyone elses work or ideas without proper
attribution. You are expected to read the handout How not to plagiarize (http://www.writing.utoronto.ca/advice/using-sources/how-not-to-plagiarize) and to be familiar with the Code of behaviour on academic matters, which is linked from the UTM calendar under the link Codes and policies.
