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.  AEC tutors can answer questions, clarify concepts, check your understanding, and help you to study. You can make an appointment or walk in anytime Mon-Thur 10 AM to 10 PM, Fri 10 AM to 1 PM, Sun 4 PM - 8 PM. For a complete schedule go to, call (401) 874-2367, or stop by the fourth floor in Roosevelt Hall.

Flash Mathlets

Here I will be posting mathlets that you may find helpful in visualizing 3D concepts. Netscape 6 or 7 will open them automatically; IE may ask you to download the free (and small) Flash Player 7 from the Macromedia site. The Player installs itself quickly and easily.

Exams and Evaluation

There will be three exams given in the evenings, 6-7:30 pm, on 2/15, 3/29, 5/3 in Quinn Auditorium. The final exam will be scheduled during the final exam period. The time and the location will be announced in class and posted on this page.

Your grade will be based upon a possible total of 650 points, as follows:

  • Three common tests at 100 points each -- 300 points,
  • Final exam -- 200 points,
  • Quizzes and Maple assignments -- 150 points.

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. Below are links to Maple worksheets for MTH 243. Your instructor will give you assignments based on the worksheets. You may find it useful to look at all of them. To open the worksheets you need a copy of Maple on the machine you are working on. Maple is available in all URI computer labs. You may purchase a student copy to install on your personal computer. If you are using Maple 9 (for example, at one of the URI labs), let Maple 9 translate the worksheets into Maple 9 format.
