Text: Bartle and Sherbert, Introduction to Real Analysis (Third Edition).

Syllabus: The course will cover material from Chapters 1, 2, 3, 4, 5 of the text.

Homework:

These homework problems will be collected for grading. Groupwork is permitted and (in most cases) encouraged. EXCEPT WHERE OTHERWISE INDICATED, group assignments may be handed in. Assignments are submitted by placing them in the Assignment Box to be found next to the elevators, North Ross 5th Floor. My normal practice is to collect the papers then post solutions. Late assignments are not accepted.
To view and print pdf you need the free Acrobat reader.

## Evaluation:

 Graded Assignments various dates (see above) 15% Class Tests October 19, November 23 30% Final Exam Examination Period 55%

Alternate Grading Scheme: Assignments 15%, Class Tests 55%, Final Exam 30%.
The scheme which gives the higher grade will be used in each case.

Note: There will be no makeups for missed tests. If you miss a test and provide a certificate indicating clearly that you were unable to write the test for reasons beyond your personal control, the weight of the test will be transferred to the final exam. Otherwise, the mark for the missed test will be 0.

The last date to drop the course without academic penalty is November 9. It is extremely important to realistically assess your course performance prior to this date.
