Course announcements may be made via email. You are responsible for monitoring your University assigned email address. No calculators or computers may be used during quizzes or exams. Weekly homework assignments are to be submitted electronically via WebWork. The WebWork page for our class is accessible by clicking "WebWork Classes" on the Math Department website, or by going to:
There will also be a computer lab component of the course which will require use of the Maple Computer Algebra System. Maple is available in the Math Department computer labs. Login information for the WebWork website and Math Department student computer labs will be distributed in the first two weeks of the semester.

Quality and Quantity of Work:

You are expected to conduct yourself in a professional manner. This includes classroom etiquette, email correspondence, and written submissions (homeworks, quizzes and exams).

Anything that you submit should be neat, legible, and clearly written.

University policy 6-100 Section 2:
"A university credit hour shall represent approximately three clock hours of the student's time a week for one semester. "
Thus, you should expect to work two hours outside of class for every hour spent in class. This is a four credit class, so you should plan to spend approximately eight hours outside of class every week studying and doing homework. The assigned homework problems are the minimum that you are required to do. Beyond the minimum, you should continue working similar problems until they become routine.



Weekly homework assignments will be submitted via WebWork:
Homework must be submitted by 11:59pm on Tuesday nights. No late homework will be accepted. Homework is scored "complete" or "not complete". You must score at least 75 points for your homework to be "complete".


There will be a short quiz at the start of class each Monday.

Computer Projects

There will be several small computer lab projects and one large computer project. We will spend some class days in the computer lab working on small projects.


There will be two midterm exams. There will be a mandatory final exam on Tuesday, December 14 from 10:30am to 12:30pm. The final exam will be comprehensive. The final will be in the usual classroom.
