Discussion Overview

The discussion centers around the differences between the TI-89 and TI-92 Plus graphing calculators, particularly in the context of their suitability for advanced mathematics studies. Participants explore features, usability, and personal preferences regarding these calculators.

Discussion Character

  • Debate/contested
  • Technical explanation

Main Points Raised

  • One participant notes their TI-89 is malfunctioning and questions whether to replace it with another TI-89 or switch to a TI-92 Plus, seeking advice on which is better for studying advanced mathematics.
  • Another participant references a source stating that the TI-89 is essentially a TI-92 Plus with a limited keyboard and smaller screen, designed to be more suitable for standardized tests.
  • A different participant emphasizes that the TI-92 is larger and has an alphabetic keyboard, suggesting it may not be as practical for some users.
  • One participant suggests that the TI-89 Titanium has slightly better specifications and recommends it for its smaller size and equal capabilities.
  • Another participant raises a point about potential differences in battery life between the two models.

Areas of Agreement / Disagreement

Participants express differing opinions on which calculator is preferable, with some favoring the TI-89 for its size and test compatibility, while others highlight the features of the TI-92 Plus. No consensus is reached regarding which calculator is definitively better.

Contextual Notes

Participants do not fully explore the implications of battery life differences or how specific features may impact usability in advanced mathematics courses.

TL;DR
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.

Thank you so much, guys! Now I know what I want!
 
One other thing to look at - batteries/battery life. May be different too.
