TI Calculator Programs 

The programs that can be downloaded directly from this page are programs which I have written. Most of my programs are also available at www.ticalc.org. I have also listed a few programs by other authors which I have found to be particularly useful. When you download a program by another author, you will be sent to a download site. I have also provided a link to a TI site where you can download new Operating Systems and Flash Apps for most TI graphing calculators. After downloading a program to your computer, if it is a zip file, extract the zip file to a folder. Then use a TIGraph Link to download the program(s) to your calculator. (I find I have fewer problems when I put all programs in the Main folder.) Most of the zip files also contain a text file which includes a description and instructions. If you have any trouble downloading or with the programs, email me at Useful sites:
