THE ACADEMIC ENHANCEMENT CENTER: The work in this course can be difficult.  You can seek help at the Academic Enhancement Center (AEC) in Roosevelt Hall. For a complete schedule go to, call (401) 874-2367, or stop by the fourth floor in Roosevelt Hall.

Exams and Evaluation

There will be two exams given in the evenings and the Final Exam:

Exam 1, W, Feb 25, 6- 7:30, SWAN AUD;
Exam 2, W, Apr 1, 6- 7:30, SWAN AUD.

Final Exam:  T, May 5, 11:30-2:30, CBLS 100.

Your grade will be based upon a possible total of 700 points, as follows:

  • Two evening exams at 150 points each -- 300 points,
  • Final exam -- 200 points,
  • Quizzes, Homework, and Maple assignments -- 200 points.

The latter 200 points are divided as follows: 70 points for Quizzes, 60 points for Maple, 70 points for WeBWorK. There will be no makeup quizzes but two worst quiz scores will be dropped.

Maple Worksheets

We will continue our work with Maple in this course. This powerful software is particularly useful in multivariable calculus to visualize graphs and surfaces in three dimensions. Maple worksheets and assignments will be posted here as we go along. The first one is already posted.

Each Maple worksheet is posted in two forms: as an interactive worksheet with the extension 'mw', say,, and in the non-interactive 'html' form. The 'mw' worksheets have been created in Maple 12 so you may not be able to open them in earlier versions of Maple. In that case, open the html version in your browser to see the content and the homework problems.

To download an interactive worksheet, right-click on it, go to 'Save Link As' and save it with the extension 'mw', say, ''. Orleft-click on it and svae what ever opens as say, ''. Once you save a 'mw' file, open it in Maple.


Note: New WeBWorK sets are posted. These conclude WeBWorK assignments for the semester.

Another Important Note: WebWorK assignments posted earlier are due March 13. I urge those of you who didn't do them yet to do it asap. WeBWorK is a part of your grade.

WebWorK login page:  Webwork login.   (Reload the page if necessary.)

Note: WeBWorK is free and does not require you to purchase any access code.
