SUMMARY

The discussion centers on the necessity of upgrading from the TI-84 Plus Silver Edition graphing calculator for advanced math courses. While the TI-84 is user-friendly and sufficient for Calculus 1 and other computational classes, the TI-Nspire offers superior performance for large calculations but is restricted in testing environments if the CAS version is chosen. Alternatives like MATLAB, Freemat, and PocketCAS are also mentioned, but the consensus is that the TI-84 remains adequate for most educational needs. Ultimately, students should consider the calculator's acceptance in testing scenarios before making a purchase.

PREREQUISITES
  • Familiarity with graphing calculators, specifically the TI-84 and TI-Nspire models.
  • Understanding of the limitations of CAS (Computer Algebra System) calculators in testing environments.
  • Basic knowledge of computational math courses and their requirements.
  • Awareness of alternative computational tools like MATLAB and Desmos.
NEXT STEPS
  • Research the differences between TI-Nspire CAS and non-CAS versions regarding testing regulations.
  • Explore the features and capabilities of MATLAB for advanced mathematical computations.
  • Investigate the use of online calculators like Desmos for classroom applications.
  • Review the specifications and user experiences of the TI-84 Plus Silver Edition for its suitability in higher-level math courses.
USEFUL FOR

Students in computational math courses, educators assessing calculator requirements for tests, and anyone considering the purchase of a graphing calculator for academic use.

So I have a TI-84 Plus Silver edition that I've had for 10 years. It's kind of beat up but it works perfectly fine. I know the model has been discontinued in favor of a newer one, and I've already encountered a feature it lacks due to its age (it was something in an introductory stats course, I don't remember anything else). Is it worth getting a new calculator that's more up to date? I'm in Calculus 1 right now and I plan to take pretty much all of the computational math classes and some of the upper division classes as well. Is there a specific type that's good for high level math?

Why not use something more powerful like MATLAB or freemat on a PC or PocketCAS on ipad/iphone or something similar?

There's also the Desmos calculator online that provides a lot of computing capability.
 
I got a TI Nspire and its pretty sweet. However its not allowed on most tests (CAS version). I also have a TI 84 and its a lot more user friendly for a newb like myself.
I will say that my buddy who is in his senior year of engineering loves his Nspire. Apparently it does large calculations in a fraction of the time. Keep in mind that if you get the Nspire CAS, it will not be allowed on tests, but the non CAS version will.

One of the expected outcomes ScienceMan may have is to be allowed pre-approved device to use in-class, maybe something already approved for possible use on tests and quizes.

..., and we may wonder about which models are allowed to be used on education regulatory tests done at testing-centers.

No. You don't need a calculator more than the TI-84 Plus Silver for your classes. Also, these TI calculators probably won't be very useful to you after you finish college since your phone is probably 1000 times more powerful, and you probably will have access to a computer for hard calculations.
