With the use of a PC, it is also possible to develop more complex programs in Motorola 68000 assembly language or C, translate them to machine language, and copy them to the calculator. The TI-89 is directly programmable in a language called TI-BASIC, TI's derivative of BASIC for calculators. However, there is no indication on the actual calculator to suggest this short-cut.

Alternatively, users can press the "diamond" shift key, followed by the number 7 on the key pad.
PARTIAL FRACTION DECOMPOSITION TI NSPIRE SERIES
Rather than having a key for the log function, users must navigate through a series of menus to find this operation. An example of this cryptic input is the base 10 logarithm function.

This design flaw, known as "cryptic input", can be a drawback for students (particularly those who are used to the user-friendly interface of the previous TI-83 and TI-84 models).
PARTIAL FRACTION DECOMPOSITION TI NSPIRE PLUS
It has a flash ROM, a feature present on the TI-92 Plus but not on the original TI-92. The TI-89 is significantly smaller-about the same size as most other graphing calculators. Additionally, some people found the TI-92 unwieldy and overly large. It was created partially in response to the fact that while calculators are allowed on many standardized tests, the TI-92 was considered a computer due to the QWERTY layout of its keyboard. The TI-89 is essentially a TI-92 Plus with a limited keyboard and smaller screen. The RAM and Flash ROM are used to store expressions, variables, programs, tables, text files, and lists. Texas Instruments has allocated 256 total kB of RAM for the unit (190 kB of which are available to the user) and 2 MB of flash memory (700 kB of which is available to the user).

The TI-89 runs on a 16-bit microprocessor, the Motorola 68000, which nominally runs at 10, 12 MHz, depending on the calculator's hardware version. In the summer of 2004, the standard TI-89 was replaced by the TI-89 Titanium. The TI-89 is one of the highest model lines in TI's calculator products, along with the TI-Nspire. The unit features a 160×100 pixel resolution LCD screen and a large amount of flash memory, and includes TI's Advanced Mathematics Software. The TI-89 is a graphing calculator developed by Texas Instruments in 1998.
