Discussion Overview

The discussion revolves around the selection of a graphing calculator suitable for high school and university mathematics courses. Participants share their experiences and preferences regarding various models, including the TI-83 and TI-89 series, as well as alternatives like the HP-46GX and TI-86. The conversation touches on usability, features, and the relevance of these calculators in academic settings.

Discussion Character

  • Debate/contested
  • Technical explanation
  • Conceptual clarification

Main Points Raised

  • Some participants recommend the TI-83 for its simplicity and ease of use, suggesting it is sufficient for most college-level math courses.
  • Others advocate for the TI-89 or TI-89 Titanium, highlighting its advanced features like integration, derivatives, and better formatting for complex equations.
  • There are concerns about the complexity of the TI-89, with some stating it may require more time to learn compared to the TI-83.
  • Some participants mention that certain teachers may restrict the use of the TI-89 in exams, which could influence the decision on which calculator to purchase.
  • Several users express a preference for the TI-89 due to its ability to handle more complex calculations and its superior graphing capabilities.
  • One participant notes that while the TI-83 can perform derivatives and integrals, it may not be as user-friendly for these tasks as the TI-89.
  • Alternative calculators, such as the HP-46GX and TI-86, are mentioned, with some users expressing satisfaction with their features and usability.
  • There is a discussion about the importance of learning the underlying math versus relying on calculators, with differing opinions on how much calculators should be used in learning environments.

Areas of Agreement / Disagreement

Participants do not reach a consensus on which calculator is definitively better, as opinions vary based on personal experience and specific needs. Some favor the TI-83 for its simplicity, while others prefer the TI-89 for its advanced capabilities. The discussion remains unresolved regarding the best choice for different academic contexts.

Contextual Notes

Some participants mention limitations in their experiences with specific calculators, such as the TI-83's capabilities in performing certain mathematical functions, and the learning curve associated with the TI-89. There are also references to the compatibility of calculators with various academic settings, which may affect their usability.

Who May Find This Useful

This discussion may be useful for high school students preparing for advanced mathematics courses, university students considering which graphing calculator to purchase, and educators looking for insights on calculator usage in academic settings.

Also, if you plan on taking the AP Calculus test, the TI-89 is a huge advantage on the multiple choice calculator section.

i use TI 84+ Silver Edition.
However i think TI 89 is more helpful.Though at that time it was cheaper than TI 84. (seriously!) but my teacher preferred TI 83, or 84 and only taught us how to use those. that's why i hv to buy 84.

You're not serious, are you? Learning the TI-89's interface/inputs is way, way easier than anything with Mathematica.

And Maple is much easier than both.

I would recommend buying a student copy of Maple for $99 (less if your campus computer store has a deal; mine has it for $20). And for class buy yourself a decent scientific like the http://www.casio.com/products/Calculators_&_Dictionaries/Scientific_&_Financial/FX-115ES/" for $15.

If you do just have to have a graphing calculator, strongly consider getting the HP 50g instead of a TI.
