TI-89 Users Group

The TI-89 Users Group was formed to provide a central information distribution point for all topics related to the academic uses of the TI-89. We are students working together to review, develop and continually improve TI-89 programs and functions for use in the fields of mathematics, science, and engineering.

Although many fine Web sites currently exist which address most of the topics we will cover, we felt that we could benefit by sifting through all the available information and organize it for quick use by our members. We will post everything that we learn. You are welcome to the fruits of our labor.

We need to emphasize that some programs were written by our members and some of them were downloaded from various locations on the Web. In our haste to put up the site, proper credit for some programs was not given to the authors. We are not claiming credit for any programs listed here. If credit is not given that means we don't remember where the program was found. If you locate one of your programs here without proper credit then drop us a line so that we may rectify the situation.

A NOTE OF CAUTION: some of the programs that were not written by us have been altered by us (for our use only). These modified programs are marked with a (modified) tag. If you want the unaltered versions directly from the authors, then go to the Links.

We are excited about the TI-89 because it will function as an educational tool for the students and as an instructional tool for the teacher.

Utility of the TI-89 Calculator Algebral System as an Educational Tool in the Training of Science and Engineering Students.

Powerful symbolic algebra, and calculus capabilities built in.

Fully programmable

Function, Parametric, Polar, 3D, Sequence, and Differential Equation graphing modes.

Pocket sized!!!

Concept of Use as an Instructional Tool

Graphing capability enables accurate representations of mathematical models

Graph data base capability allows for instant recall of stored demonstrations

Programming capability enables quality demonstrations

Graph link gives ability to share programs

New semester coming up. First meeting will be announced via flyers.

You will need Adobe Acrobat to read some of the pages on this WebSite. It is a free download.

You will need a program to expand .zip files and a TI-Graph Link cable if you want to download the programs from this site directly to your calculator.

EasyZip2000 3.0 is a free download that will unzip files.

WinZip is shareware.

TI Graph-Link 89 is a free download from Texas Instruments. You will need this program to read the downloaded calculator programs even if you don't have a TI-Graph Link cable.

Instructions

There are two ways to get these programs into your calculator. With either way you must first click on the link and save the program or .zip file on your hard drive. Make a note of the location where it is saved. If the program is part of a .zip file then the zip file contents must be expanded into a directory on your hard drive. Now proceed to step one or step two.

1. If you have a graphlink cable you can connect your calculator to your computer. Instructions for this are included with the cable. Open the GraphLink program, select Link: Send: and then find the programs on your hard drive to send to the calculator. Send them to the calculator directory where you want to store them.

2. If you don't have a graphlink cable you must type the programs in by hand. Open the GraphLink program, select File: Open: and then find the program you just downloaded to your hard drive. Open it. Now that you can read the code, just create a new program on your calculator and type in the code. This can be tedious for some of the longer programs, but it is possible to have any program on your calculator without buying a graphink cable.
