The title basically sums it up. Which one of those two is better?
Thanks for any info.

Go get an fx-CG instead. :thumbsup:

If price isn't a problem definantly go for the nspire. The nspire can do everything the casio can do basically, plus a computer algebra system. :rolleyes: I have the basic nspire. (I'm still spanking myself for not getting cas.) It blows every calc away as far as speed, and screen( the new prism may be better), and the best UI I have ever seen. If you have any questions just ask.

It is important to make proper comparisons. The high end non-cas TI calculator is the plain nspire. It's competiton is the Casio Prizm which is also a non-cas calculator, but because of the new color screen technology that Casio has, combined with better programing and other features, the Prizm is much more desirable compared to the npsire model that you purchased.

The high end cas TI calculator is the nspire cas model and its competition is the Casio Classpad which has vastly superior math capability, and a much easier to use UI. If you like nspire cas model, you would love the Classpad.

No doubt TI is scrambling to come up with a color screen for their nspire and in the mean time the tactic seems to be to point out that you don't need a color screen to do math. While that is true, it is like saying that you don't need a color screen to watch TV. If you have ever watched black and white TV, you know what a stale experience that is.

No doubt Casio is working on upgrading their cas Classpad model with a color screen and because Classpad already has math superiority over the nspire cas, the thought of a Classpad with a color screen probably causes the people at TI to lose control and soil their underware.

A color screen with good battery life is a major technological break through that will determine the winners and loosers in the next generation calculator business for quite some time to come. While TI has been plugging their outdated designs with catchy advertizing spin, Casio has been quietly improving their product and has now jumped ahead of TI technologically. The basic nspire that you bought has never been real popular, and TI has attempted to cover that over with advertizing spin, but now that the competiting model has a color screen, there doesn't seem to be much future for the plain nspire. In addition, if Casio introduces a color screen version of its Classpad in a timely manner, that would make it quite difficult for TI to sell its nspire cas model which is a warmed over TI-89 design of more than a decade ago. :greengrin:

The only "innovation" of Casio's Prizm is new display - nothing else. There is no better programming - it has the same stupid limitations no physical constants, no multiletter variables, no procedure params etc. Simply programming is the same... The Casio calculators are very limited also in mathematical calculations - you can't compute Integral of Integral etc... Again limitations are the same as with old 9860G

That's true. Read manual or try to compute this and you will see. The same problem is with sum. You cannot compute Sum of Sum etc. This calculator is suitable only for a primary or secondary school, but definitely not for a university...

Open manual from http://edu.casio.com...fxcg10_20_E.pdf and read:
* Page 2-32: You cannot use a first derivative, second derivative, integration... inside of an integration calculation term.
* Page 2-32: You cannot use a first derivative, second derivative, integration... inside of an Sum calculation term.
As I've written before, the same problems and limitations as with old 9860G

If you want to do calculus operations such as derivatives and integrals you need to spend more money and buy a cas calculator such as the Classpad or nspire cas model. The Prizm and the nspire are graphing calculators but they are not cas calculators. The Prizm programing is less limited and easier to understand than the nspire programing and if you need some constants nothing stops you from storeing them. As for multiletter variables, that is unnecessary and insignificant. What specifically do you mean by procedure params etc? You seem to under rate the significance of a color screen. Have you actually seen and used the Prizm? What calculator are you presently using and what math courses you are taking?

I don't want CAS, I want numerical solution not symbolic. HP and TI are able to do compute this at least for 7 years. Casio unveils completely new calculator with fast cpu and huge memory and isn't able to compute this.

What specifically do you mean by procedure params etc?

If you want to create common subroutines, libraries you must have local variable and procedure parameters to isolate them from "surrounding". Global variables are not sufficient. That is the main reason, why for Casio calculators don't exist good engineering applications.
I use Casio 9860G I've bought for discount price, but I'm really disappointed with it. Next time I would buy HP50G.

Y1=Integral(X,0,X)

Slow, but works.

The ti nspire basic does both definite integrals and derivatives (up to the second order) if they are numeric. The new ti 84 os also had those functions. Multiletter variables are also well supported by the basic nspire, and in no way are they "unimporatant and insignificant".

By the way here are some facts found on unitedti.org
TI-Nspire
90 MHz processor (150 max)
320x240 screen
15 level grayscale screen
~16384 KB of user RAM
~16384 KB of user archive

Prizm
29 MHz processor (the max is between 58 and 116, from what I heard)
384x216 screen (lower height but larger width)
8 colors in BASIC, 65536 in images and possibly ASM/C, once it's hacked (if it's possible at all), but for now, all we have is 8 colors.
~61 KB of user RAM
~16384 KB of user archive

"Y1=Integral(X,0,X)
Y2=Integral(Y1,0,X)

Everything about the nspire is instantaneous.

Perhaps I could insert a note of humor here. Everything about the nspire is instantaneous except learning how to use the thing, and especially how to to use it's complicated programing scheme which I havn't been able to figure out yet. :roflol:
More seriously, try integrating x*sin(x) from 0 to one, or taking the derivative of x*cos(x^2). Those are some very ordinary text book calculus problems.

It is correct that Prizm is not a good choice for college math but neither is the plain nspire model. For college/university courses where a calculator is allowed, the best choice is a cas calculator such as the Classpad or Hp50g. The nspire cas model was designed with high school teachers in mind and lacks a lot of math that the Classpad and Hp50g have. :rolleyes:

Instantaneous?... it seems you haven't realy been working with the Nspire yet. :blink:

Just try to create/open a document which is 50Kb large and to type things...

Ok, so basically you're saying that my choice should be either the CAS Nspire or the Classpad, with the Classpad being the preferrable alternative (as I need them for the uni)?

the class pad is awesome--but i ditched it because ot the unreadable screen. i think casio will not release another pen calculor--but a color class pad would be amazing
