TI-89
Advanced graphing calculator
The TI-89 is a graphing calculator made by Texas Instruments, widely used in high school and college math courses.
More advanced than the TI-83 and TI-84, it handles symbolic algebra, calculus, and 3D graphing: The TI-89 can solve integrals and derivatives symbolically.
Some standardized tests ban it for being too powerful.
