Since there are many preliminary topics that were treated in the prerequisites, I will review and revisit these topics first. My lectures may or may not follow the order or the presentation in the text. It is most important that you take good class notes. Please pay attention to the differences between my presentation and text’s. I will make my lectures self-contained and will presume that you had math maturity but little prior knowledge. From time to time, I supplement my lectures by handing out class notes. Obviously, it is important that you read these handouts. Needless to say, good attendance will enable you to receive therefore understand these handouts, and I do check attendance.
Our course material development is formal but with an intuitive appeal. Most proofs are constructive in nature.
I believe in active learning, namely learning is a two-way street. Therefore, I encourage the class to ask questions. My answers, most of the time, will be another question --- a leading question. I expect you to read the course material we cover in class either before we meet in class or after class, PREFERABLY BOTH.
I collect homework every week. You are encouraged to DISCUSS with your classmates about course materials, homework etc, or get help from me. Copying somebody else's work is prohibited.
I do not give make-up exam. If you have legitimate excuse, AND you obtained my prior approval, your course grade then will depend on homework and final.

Any student who has a need for accommodation based on the impact of a disability should contact me privately to discuss the specific situation as soon as possible. Contact Disability Resources and Services at (215) 204-1280, 100 Ritter Annex, to coordinate reasonable accommodations for students with documented disabilities.
Freedom to teach and freedom to learn are inseparable facets of academic freedom. The University has adopted a policy on Student and Faculty Academic Rights and Responsibilities (Policy # 03.70.02) which can be accessed here.
Students will be charged for a course unless a withdrawal form is processed by a registration office of the University by the Drop/Add deadline date. The Drop/Add deadline date is published in the Class Schedule each semester. A student may not withdraw from the same course more than once. Students who miss the final exam and do not make alternative arrangements before the grades are turned in will be graded F.
