Derive
Basics:
 Chapter 0 of the lab manual is available online as an Adobe PDF document.
Just click the "Derive Basics" link on your left and it will be
displayed in a new window. (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
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.

 The lab is open for students working on their lab assignments at various
times each week. See the link "Lab Schedule" on your left for
the details.
The older version of Derive is also available in the K214 PC Lab. Locate the
'Class\Derive' folder and doubleclick on the startup icon. You will need to use a floppy
disk to save your work. This lab is opened longer than PSB208. See their home page for the exact schedule.
 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. The default directory should be the H: drive, if not
then 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 confidential. For example, don't write it down next to
your account number in your manual where others can see it.
 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.
 Purchasing
Derive 6:
 We are using Derive 6 software in the lab. The software is not required for the class
but it is an excellent software package and it's sold at a reasonable price. It will allow
you to work on the labs at home and it will be useful for all of your math and science
classes.
 The Soft Warehouse, the developer of Derive, have become part of
Texas Instruments Incorporated. They have an online
store where you can purchase the latest version of Derive for a student
price. Click to see TI's Derive web page. The UH Bookstore computer counter also has
the latest version for a similar price.
Note:
If you have your own version of Derive you will need to copy the utility
functions on to your computer. See below.
 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 ADDUTIL.DFW
and ADDUTIL.MTH at the bottom of that page.

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.
