**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. Worksheets for maple
assignments to be graded will be assigned in class.
The assignments will be based on the maple worksheets below.
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.

of Functions of Two Variables "(graphs.mws)

**Information on Maple 9:**
If you are using Maple 9 (for example in the library), let maple 9
to translate the worksheets from our web page into the maple9 format.
Then the worksheets will work fine.

A general info on maple worksheets:
When transferred over internet (including email), any maple
worksheet must be treated as a binary file.
Also, the name for the number pi in maple is 'Pi'. 'pi' is used
to name a number theoretic function and will give you an error message
(usually 'not able to evaluate your fuction' message).

**Available Help** In addition to your
instructor's office hours, the Mathematics Department has an extensive
system of walk-in help sessions scheduled in Roosevelt Hall.
You can find the schedule by

Our Maple helpers are available at the Mathematics Department CyberLab,
Tyler Hall, Room 101. The schedule is posted below.
