Lab Usage:
-
Terms of Acceptable Use:
-
Each student must agree to the Terms of Acceptable Use statement for the
UH Math Dept Computer Lab. The students agree to obey all of the terms of use
and conditions set forth in the UH Information Technology Resources Policy.
Their policy is here:
http://www.hawaii.edu/infotech/policies/itpolicy.html
The policy for the math lab will be the same, but adds in particular that
Students agree not to:
1) Download, install software or run any outside
programs or software packages.
2) Download or upload work protected by copyright or files not related to
class work.
3) Attempt to gain unauthorized access to remote computer systems.
In addition you acknowledge that:
4) There is no expectation of privacy in the Math Lab and your activities may
be monitored.
-
Accounts and passwords:
-
Each lab account can use a portion of the network hard for storing files.
You save your files to the H: drive and
not
the local hard disk or C: drive. In Derive you would typically save your lab
by using the Save As ... option
on the File tab and then saving you file with the name
H:\lab1.
To open a file you would use the Open
option on the File tab and enter
H: <cr>
to see a list of your files.
In order to keep others from using your account you need to keep your
password secret. For example, don't write it down next to
your account number in your notebook where others can see it.
Graphing and Calculus Software
wxMaxima:
-
Download wxMaxima: (click to
view info)
- You can download this free software which is available for Window, MacOS,
Linux and UNIX computers. This software is installed on the lab PCs and is
used in the calculus classes for graphing and symbolic calculus
calculations. In addition, the math department has many sample sessions
available on their website.
Derive 6:
- Derive
Basics:
- The Derive 6 software is installed on the lab PCs. There is an
online lab manual
available on the math dept website for learning to use the software. In particular, Chapter 0 of the lab manual explains the
basic usage techniques. (Note: You need to have the Adobe PDF reader
installed on your system. Click the icon below if you need to install this plugin.)
-
Online Derive Demo:
(click to
view)
- You can view and download videos from the math department website. These
videos show how to get started using Derive 6. You will need a Windows PC with
sound capabilities and you will need to install some video software in order
to view the videos. After installing the video component software you can use
the links below to listen to the videos. The videos are available on a CD in
Keller 419.

- Utility
Functions:
- We use a special collection of interesting new functions for the lab. They
are contained in a Derive utility file. Click on the "Utility Functions" link on your
left for a discussion and examples of their use. If you use Derive at home you can
download the required files ADD-UTIL.DFW
and ADD-UTIL.MTH at the bottom of that page.
- Purchasing
Derive 6:
- The software is not required for our classes
but it is an excellent software package. Unfortunately, it is no longer sold by Texas Instruments.
It should be possible to obtain a copy online from Amazon.com or other
supplier.
Note:
If you have your own version of Derive you will need to copy the utility
functions on to your computer. See above.

Other Free Graphing Software:
- Online
Grapher: (click to try)
- Try out this online grapher. Be sure to use the * character for
multiplication and you zoom in on a point by dragging your cursor to form a
rectangle around the point.

- Download
Winplot Software: (click for instructions)
- Winplot is a small but useful plotting program that can be downloaded and
used on any Windows PC. It is available on the desktop in the PC lab in addition to
Derive. Give it a try!
Mac users with OS Version 7.5 or later already have a plotting program on
their Apple menu. Check it out.
Other Free Software:
- Just
for fun ... read
about an important math/computer problem:
- The famous problem "P versus NP" problem is decades old and
there is a million dollar prize to solve it. Now a mathematician in
England has shown that the problem is equivalent to solving a larger
version of the well know Minesweeper game that is included with the
Windows operating system. Read the news
story, Scientific American article or just play the
game.
