Hi guys! I was looking for a new graphic Calculator to buy. Any suggestions??

[LordNPS]

9860 for sure, no doubt

[Khỉ con]

Yes, at now, TI-89 Titanium. In future, TI nSpire CAS+.

[Huz]

Ok guys Thanks for the replies. Can anyone enlighten on the difference between FX 2.0 and the new 9860G? Which one is better guys? Even 9850 with colour screen looks cool!

[Khỉ con]

No need color LCD. FX 2.0 is better.

[Huz]

No need color LCD. FX 2.0 is better.

In what way is FX 2.0 better. I mean what FX 2.0 plus has that 9860G doesnt?

[Khỉ con]

FX 2.0 = CFX-9970G

[Khỉ con]

No, I don't like it.
It's no BEST.

[Huz]

okay I am still not sure. Can 9860G do algebra? It also lacks some of the applications which FX 2.0 has.

[Khỉ con]

FX-9860G is not CAS.

[vanhoa]

At first I hope you please dont me or if you see any not-right English on this

FX-9860G has Algebra ( the nature textbox I/O ) ! But it have no CAS!

I think it is not very useful for you if you are student. Else you will it very useful for your work with, at first, HI-SPEED CPU, the second,Spreadsheet and the third, E-activity.

If you are student, then I suggest you should make a choice: CP or TI.

Classpad is a very-easy-to-use calculator so you can evaluate what you want: CAS or Geometric and such on. It also have a large face that make us very-easy-to-watch and a pen that ve ry moden. But program on it is not good at all.

Ti is very good at program, we can do activties very fast with its buttons. And it is also very good at comunication with the cable goes with it. This is my problem because in my country I cant see a place to buy SB-87 so I must use my hand, that is a very terible job

Ok, that is my opinion.

TI-89 Titanium is best choice. But in Vietnam... hix...

9860 is the Best calc in its class
9860 does not "lack" CAS, it is meant not to have CAS, it is not a failure or a bad charecteristic.
When you say "9860 doesn't have CAS" it gives the calc a bad conatation, it is harmful.
It is the best calc, the only reason it doensn't posesse CAS is because it would be unavailble for HighSchool, as it is required for calcs not to have CAS.
There's no other Calc, Ti or Casio that overgrows 9860 in any manner within a 100? class price (apart from CAS)
What you have to ask yourself is if you're willing to have a Calc (like Fx 2 or Ti 89 ) that is not ( I am sorry, I love AFx2 very much too, however it is the sad truth) nearly as fast as the 9860 (3x slower) in exchange for CAS.

9860 is the Best calc in its class

I agree.

First you should decide on the types of features and functions you want out of your graphic calculator, and not decide on the brand first. This is like deciding your needs and budget for the car you want to buy, then go look for those models within your requirement.

Now I would put some requirement into perspective:

Firstly 9860 would be in the same class as the TI-84+ and perhaps HP9g or 39GII, since all these models do not have CAS and are allowed in most major examinations such as IB, Australia examination, AP, and so on. I

Price: surely 9860 and HP9g is at least 10 % cheaper than TI-84+

Speed: In this department both TI-84+ and 9860 are very much the same. Way better than HP9G definitely.

Special Features: While HP has a nice aplet feature, it is very complicated to use. the Casio 9860 eActivity is a very easy to use and powerful feature, if you know how to tap its power. No programming knowledge and formulation is required to create a eActivity. TI-84+ applet is very good too as long as you have good formulation knowledge to create a good applet.

I suppose the main attraction is the available memory of 1.5MB in the 9860. And if you think you want more power, you can get the 9860G SD model which allow the plug in of a SD card.

I have both AFX 2.0+ and 9860G, I can attest that 9860 is way faster than AFX.

Another class of calculator would be TI-89 series, ClassPad and HP 39G and so on. Of course, TI-89 and ClassPad are way much better than HP CAS calculator in terms of ease of use, function and design. Although, I know many engineers like to use HP graphics calc.

[vanhoa]

So at all, 9860 is the best calc ?!?

I think the best calc folows your job and your favorite.

With program, Ti is the best and then 9860.
With math, Ti and CP is the best and then AFX.

But 9860 will good when you like it!

[caspro]

I've just got hold of a 9860 and a classpad.

The black-white contrast on the 9860 is miles better than any other calc.

All other casio calcs have very grey or green looking screens.

You have to see the clear 9860 screen to believe it.
The natural display input is a bit of a gimmick though, since all results are still numerical.

Having seen the amazing 9860 screen, I was disappointed to try the classpad and find the screen
was very hard to read ( yes, I tried adjusting the contrast), due to very small font as well
as grey-green screen.

If the classpad had the screen quality of the 9860 then that would really be something.

[Khỉ con]

ClassPad 300 Plus, new high contrast display.

[caspro]

ClassPad 300 Plus, new high contrast display.

Thanks for that.

Damn. If the Classpad 300 plus exists, why are they still selling the Classpad 300.

Is it as clear as the 9860 though ?

Am currently preparing for SATs Exams i.e. SAT I Mathematics and SAT Subject Mathematics Level 1 and a graphical calculator is particularly useful. (We are not allowed to use calc in school so this only for sat). Any recommendations??

For those of you who dont know, the content of study is:
Number and operations; algebra and functions; geometryand Measurement (plane euclidean, coordinate, three dimensional, and trignometry); statistics, probability, and data analysis.

Acceptable Calculators
Calculators permitted during testing are:

graphing calculators
scientific calculators
four-function calculators (not recommended)

Unacceptable Calculators
Unacceptable calculators are those that:

use QWERTY (typewriter-like) keypads
require an electrical outlet
"talk" or make unusual noises
use paper tape
are electronic writing pads, pen input/stylus-driven devices, pocket organizers, cell phones, powerbooks, or handheld or laptop computers


I didnt mention this before to keep the topic unbiased.

The fx-9860 can handle all of that. Especially with its natural textbook display, algebra would be easy. You could download the Geometry add-in from Casio's website and the fx-9860 has built in software for statistics and data analysis.

If you need a calc in a hurry and learn how to use it quickly for the test, get the fx-9860. The GUI menu makes its easy to use get comfortable easily than a TI calc.

In that case you should be looking at FX-9860G or TI-84+. Both are fast calculator and have the power for your study. Though 9860 can cost up to $15 less.

[Huz]

Thanks But the loop hole here is that SAT allows Calculators with CAS. So the question is does having CAS really makes a difference or whether it is required (i have no prior knowledge of Graphic Calculators.)

Here let me give an example of a problem:

If f(x)= x^4 - 3x^3 - 9x^2 + 4, for how many real numbers k does f(k)=2?

a. none
b. one
c. two
d. three
e. four

can someone solve this? Does having CAS here provide added benefit?

[TomL_12953]

Thanks for that.

Damn. If the Classpad 300 plus exists, why are they still selling the Classpad 300.

Is it as clear as the 9860 though ?

It could be that they have a large inventory of the older one to clear out. If you look at the prices, the older one is cheaper than the Plus version now.
