Hello...
I am chilean, and need to buy a calculator.
you can help me to buy?

i have calculus, algebra, fisica, linear analisis,=integrals, derive, vectors,function trigonometricas etc..

what calculator is for me?

always i have casio...but standar..

is the casio powerful or just as the HP or ti?

and the last question is if the casio have solution step by step or graphics mode?
for example the hp 49g you see the formula integral and only you have is put the data, and then you see how the result is done. step by step.

thank and sorry my bad english

i dont know much about the hp 49g thingy, but that thing about the showing the work sounds pretty cool.

i personally only own a CFX-9850 GB+ and you might be able to use it for your algebra, and probably calculus, the others i don't know any thing about (i'm only and lowly 10th grader), maybe you should check out the AFX 2.0, but i don't know exactly what it can do, so might probably want somebody elses opinion.

is the casio powerful or just as the HP or ti?

ouch, personaly i think that the TI's are pieces of crap. don't get me wrong, but the Casio's are a much better deal for the money. but my friend has a TI Voyage (an upgrade of the TI-92), and it is nice, although it dosent do colors and still only programs in basic, even he wishes sometimes that he had a Casio.

i don't know diddly squat about hp's.

the TUTOR program on the AFX 2.0+ shows work.

[huhn_m]

You can't do real Algebra with CFX9850GB+. It only solves terms with X
but is not capable of simplifying / expanding terms or of the Usage of
terms with more than 1 unknown variable.

WHAT?!?!?!?!?!?! CAN THE AFX EXPAND TERMS??

Is this TRUE?

[CrimsonCasio]

hehe, yep.

The AFX2.0/Graph100 has CAS. which is algebraic manipulation.

However, this is not integrated in with the operating system, but works like a separate program..

The TI89/92/V200 has a more powerful CAS system, which is 100% integrated with the OS, +they have more functions and are more advanced in general. TI also has official programming support, if you're interested in that..

I've never used an HP myself, but from what I hear, it's a very powerful and "professional" calculator. The hardcore fanbase claim it (HP48/49) will leave any calculator looking like shit

Personally I have an AFX2.0, and I'm quite happy with that. The non-plus models don't have vector, list and matrix manipulation in CAS mode, so make sure to buy a plus model if you go with this one

[CrimsonCasio]

or of course you could go all out and get a ClassPad 300.

[Cernic]

thank! all!

i thing to go for the algebra 2.0 plus... only for money/performance...

the hp or ti.........HIGH PRICE!! THE HP 49G IN CHILE US$ 210 AND THE TI89 US$250 DOLARS

THE CASIO ONLY 100 DOLARS......

only one question....
the casio afx+ is capable the show me the result the integral step by step?
or only show the result...?skipping the factorize, properties the integration,etc...?

THANK!

[CrimsonCasio]

your welcome, make sure to stick around and we will be happy to help you with any problems you might encounter.

The 68k line of calculators (TI-89, TI-92, and v200) can be programmed in assembler or C on the PC. As is the case with the AFX2, programs compiled to machine code on the computer and uploaded to the calculator are many times faster than Basic.

I own an HP-48gx. RPN is very nice once you get used to it. Its not as user friendly or easy to use as a TI or Casio but it can do lots of things I havent seen the other calcs do. (Think about the comparison between DOS and Unix). The only thing I really dislike about it is the slowness of displaying menus. We ran some speed tests on another forum. Both the TI-89 and the HP-48gx have a key to display a file manager. This is roughly equivalent to the AFX program menu except that it shows all variables, matrices, programs, etc. The TI-89 shows the menu in about 0.6 seconds while the HP-48gx takes around 3.5 seconds. You can find a similar delay on all screens the HP-48gx shows (Graphing, Equations, Settings, etc.). However, this doesnt say anything about calculation speed. The HP-48gx beat even the TI-89 in speed of calculations. I have heard that this problem with display was a major complaint with HP-48 users and that everything displays roughly 10 times faster with an HP-49g. I havent used one so I cant tell you how accurate this is.

At less than half the price of the TI and HP I think the Casio would be worth your money.

alephmorpheus how well is the term expansion feautre integreated into the HP?
