12/15: Course is over.

Syllabus: We plan to cover the following topics, most of which are related to chapter headings in the textbook. (In some cases, there will be handouts to supplement the textbook.)

Prerequisites: Math 213. In particular, you are expected to remember something about writing proofs, although the course itself will provide a lot of further practice.

Course grade:  This will be based on the following weighting: homework (25%), first midterm (20%), second midterm (20%), and final exam (35%).

Homework: Homework assignments will be posted on the bottom of this web page, and are due at the start of class for each due date. No late homeworks will be accepted. Exams:  There will be two midterms and a final.  

Attendance: Since you will be working in groups, your workmates can get frustrated if you regularly skip class and then cannot meaningfully contribute to the homework.

Course conduct: To respect everyone's right to a productive learning environment, please refrain from disruptive activities during class. This includes reading newspapers or magazines, and using pagers and cell phones. Set cell phones on vibrate mode only. If your cell phone receives a message, you can check it after class. Please turn off all other electronic gadgets before entering the classroom. On a positive note, do feel free to ask questions!

Academic integrity: Students are expected to avoid academic misconduct. Your integrity is not worth losing (and the course not worth failing) by falsely presenting yourself in any aspect of this course. For further information on academic integrity, see Part VI of the Student Code.
