Graphing Calculator Programs
These programs are ACT compliant and ready to be loaded onto compatible TI-83 and TI-84 calculators. They may also be allowed on other standardized tests - check with your school or testing organization.
The programs are available as .8xp files that can be transferred directly to your calculator. However, the process of installing them can be difficult to do. If you prefer, the program code for all is included in a document below. For each, create a new Program using the PRGM key and enter the code below using the PRGM:I/O menu and the main calculator keys. A tutorial on basic TI-84 CE calculator programming can be found here: Click Here
