TI-DOWNLOADS
The programs below are for the TI-83 graphing calculator from Texas Instruments. The GUESLINE program was originally created by George Egbert and later modified by Dr. Michael Lloyd, Henderson State University. The POLYSOLV programs were written by Dr. Michael Lloyd.
Using GraphLink software from Texas Instruments, you can download a program from your computer to your graphing calculator. In the list below, click on 'DOWNLOAD' to save the program on your computer. If this is the first time you are downloading a TI calculator program, or if you do not have GraphLink software, you can find help on the instructions page located on the Texas Instruments Web Site.
The textbook chapter or section to which a program applies is noted.
