FINAL EXAM: Thursday, May 5 (Chapters 11,12,13,14)


1. Attendance: students are expected to come to every class. Each lecture will include new material. While I will take attendance daily for control purposes, there is no mandatory attendance requirement.

2. Course log: This link to the course web page will contain a brief listing of the material covered in each lecture, handouts , announcements and homework problems. It will be updated after every class and should be consulted often. I wonít be using Blackboard.

3. The most important concepts and examples for each topic will be presented in class, but for thorough understanding you are expected to (i) read your textbook and your class notes; (ii) work on the homework problems; (iii) ask questions when there is something you donít understand. I will assume students have read the text in advance, so I can spend most of the lecture on examples and problems. Some sections in the book have been assigned for independent reading.

4. The link classroom behavior expectations includes a list of behaviors considered disruptive (math department policy). Please familiarize yourself with it, as this policy will be enforced. This includes: no laptops, cell phones off, no texting allowed during lecture and no reading extraneous material.

5.HOMEWORK- Homework will be collected and graded each week (about 5 to 8 problems/week).Homework problems posted on the course log by Wednesday are due on Friday, at the start of class. Late homework wonít be accepted.

6. EXAMS- There will be two in-class written exams and a final. All four grades (including the homework grade) will count towards the course grade, with equal weights (25%) Expected grading scale: below 50: F; 50-54: D to C-; 55-69: C or C+ 70-84: B or B+; 85-100: A- to A. I do not `grade on a curveí.

Students with disabilities: please contact the Office of Disability Services (2227 Dunford Hall, 974-6087 V/T) if you need special arrangements for this class.
