Homework The only way to learn mathematics is to solve problems yourself. This course will therefore involve a great deal of homework, in two different formats:
    Paper homework: a set of problems from the text is assigned for each week, and must be turned in on the assigned due date (usually Tuesday), in class. Late homework will not be accepted. 

    Be sure to check the web for revisions before starting each homework assignment.

  • Web homework: You need to register at

  • Go to this page and bookmark it. Then follow further online instructions.

    Most weeks, you will need to do an on-line homework assignment. These will be due on Sunday nights at midnight. 

    • To move from one problem to another within an assignment, click on the next and/or previous buttons which are displayed within your browser screen.
    • When you have finished the assignment, click on the grade button. You will immediately be informed of your score for the assignment. Each assignment is worth a total of 15 points. 
    • You are allowed do an assignment several times. In this case, your grade for the assignment will be the highest of the scores for your various attempts. There is at present no penalty for attempting an assignment several times. Unfortunately, however, this policy has made it necessary to disable the feedback feature of the e-Grade system. 
    • Wiley is asking for your opinion of the e-grade system. Please go to their survey page, and let them have it.
It is often a good idea to work together with others in the class. However, since homework earns credit, it is understood that everyone submitting particular problems has solved them individually. 

Remember: trying to learn the material just before the exam rarely produces good results in any math course! 

Grading: This course will entail two in-class mid-term exams and a final. By enrolling in the course, it is understood that you are making a firm commitment to be in attendance on the dates of these exams. Your course grade will be based on your exam scores, paper homework, and web homework, weighted as follows:
Paper Homework 10%
Web Homework  15%
Midterm #1 20%
Midterm #2 20%
Final exam 35%
