What's the difference between Ti-89 and Ti-92 graphing calculators?

  • Thread starter Math100
  • Start date
In summary, the TI-89 and TI-92 graphing calculators are both advanced tools for mathematical computations, but they have key differences. The TI-89 is more compact and portable, featuring a smaller screen and a design optimized for handheld use. It is primarily focused on algebra, calculus, and engineering applications. The TI-92, on the other hand, has a larger screen, a more user-friendly interface with a QWERTY keyboard, and additional features like a built-in stylus for graphing and note-taking. The TI-92 is better suited for users who require a more extensive display and functionality for complex calculations.

TL;DR Summary
What's the ultimate/huge difference between a Ti-89 (Titanium) and a Ti-92 Plus graphing calculators? Which graphing calculator is better for a student who studies advanced mathematics?
Currently, I own a Ti-89 (Titanium) graphing calculator but it doesn't seem to work, I've replaced new batteries and it still doesn't work because the screen is still blank after I pressed the 'On' button. I used this graphing calculator for more than 10 years and I think I should just buy/purchase a new one instead of fixing it, although I'm not sure if this can be fixed. My question is, should I get another (same) Ti-89 (Titanium) graphing calculator again or buy/purchase a Ti-92 plus graphing calculator? What's the ultimate/huge difference between these two graphing calculators? Which one is better and more suitable for a student like me who studies advanced mathematics? Right now, I study "Nonlinear Ordinary Differential Equations" and don't know if Ti-92 Plus will be a better choice for me. In terms of thinking/planning for the near future, should I get the Ti-92 Plus instead?

Per wiki: https://en.wikipedia.org/wiki/TI-89_series

The TI-89 is essentially a TI-92 Plus with a limited keyboard and smaller screen. It was created partially in response to the fact that while calculators are allowed on many standardized tests, the TI-92 was not due to the QWERTY layout of its keyboard. Additionally, some people found the TI-92 unwieldy and overly large. The TI-89 is significantly smaller—about the same size as most other graphing calculators.

The TI-92 appears to be pretty large and not usable on many standardized tests. The TI-89 Titanium appears to have slightly better specs. Personally I'd stick with the TI-89 Titanium due to its smaller size, apparently equal capability, and slightly better specs.

The 92 is an 89 in a bigger box and with a alphabetic keyboard.

One other thing to look at - batteries/battery life. May be different too.
