I'm deciding to switch graphing calculators after spending the better part of 4 years with my TI-83. I'd like to stay with TI (I was never a huge fan of Casio, but I will say that the PRIZM is great). I've considered two calculators: TI-89/Voyage 200 - Very powerful capabilities, but a little on the expensive side TI-Nspire CX CAS - About the same as above, just with a little brighter display (I love using the Nspire GUI and am familiar with it despite what people say) Any suggestions?
I got my HP-48G 16 years ago and still use it on a daily basis at work and home. best. graphing. calculator. ever. i dumped by TI-85 in the mid 1990s for it.
isn't it amazing that graphing calculators are 15 yr old technology... yet still costs the same as an iphone...
Never used an N-Spire but TI-89 is quite powerful and can do everything you would need it to (probably) at a cheaper price.
my calculator cost me peanuts at a pawn shop. Pretty new TI-89 cost me 10 bucks because apparently it's not as in demand as the 83s
I never remember needing anything beyond a TI-30 for calculus. If you're in engineering you'll need a TI-89ish calculator for some classes...the solve function is a huge help with systems of linear equations... classes like engineering math, statics, and circuits are a lot easier with it.
The Nspire is an absolutely amazing calculator. Definitely the best one I have ever used. I recommend that one.
