TI-89 Software

Some programs for the Texas Instrument Calculator series TI-89/92/200 were written partly by Benjamin Schmid and partly by myself. You can use and modify them as you like. They are intended to help you with some of your math or statistics problems, but we do not give you any warranty for correct results.

Most programs are written in a way, that you not only get the final result, rather you get all intermediate results to help you learning some math techniques and prove your own hand-written calculations.

All listed codes are exported with TI-Graph software. You can also import these ASCII-files, modify them and make your own TI-Programs or you simply download the binaries.

Some good resources about the calculator:
