    Casio FX 570-ES

Posted 23 March 2016 - 06:02 AM

Hey there,

 

I need some help choosing which calculator to get.. I'm torn between FX 2.0 Algebra, FX 9860GII SD & TI 89 Titanium

I'd like to know which calculator has a text editor / or it has something that allows you to type into it and save it.. for things like storing formulas and equations, before you accuse me of cheating.. my teacher allows it.

 

I know that the 89 and algebra has CAS, but frankly I wouldn't need this as much as saving formulas and stuff, doing most of algebraic stuff on my own is easier and more enjoyable

 

so the main question here, which of these I should get if I want to store information into the calc? which has more space for typing, etc?

 

thank you very muchz!

 

J

The FX-9860GII has a text editor, you can use the in-built program editor or install a proper text editor add-in for it, which can also be saved to the SD card as well as the calculators main memory.

 

Since I only have the 9860GII and I am currently developing programs for it I am biased towards the 9860GII.

But either one won't have space problems when it comes to storing text right? I'll most likely have to go with the 2.0 cause GII is out of stock at the moment. The GII has more programs than the 2.0 right?

The Algebra FX (common abbreviation around here: AFX) has about 140 KB of RAM and about 750 KB of flash memory. The 9860 has 64 KB of RAM and about 1500 KB of flash, and there is a version with an SD card slot. Programs (which can be used to store texts, just type the text instead of proper code, and simply never run the program) are usually stored in RAM, but they can be backed up into the flash memory or onto the SD card (if present). If you add all memory together, the 9860G SD and 9860G II SD win, followed by their non-SD counterparts. On top of that, the AFX is simply a lot older: quite a few bugs, no OS updates possible because the OS is not on a flash chip but true ROM (read-only memory) so these bugs can't be fixed, poor integration (next to non-existent) between the algebra system and the rest of the calculator, and it's as slow as the even older CFX series; the 9860 is at least twice as fast. You will feel the difference, and if you need the algebraic capabilities in the future, there are several computer algebra systems for the 9860 floating around the web. Go for the 9860. I say that as an AFX owner. Oh, almost forgot: the 9860's flash is said to be much more durable than the AFX's. Mine broke a few years ago ... and it seems the flash is the broken part.
The AFX was a good calculator when it was new. But it isn't new anymore. Its time is over.

So, overall the AFX isn't worth the money? Regarding space and performance and stuff... I'm not sure.

 

What I had in mind was to get a calculator that is good enough to store some formulas and reminders on calculator and also CAS to save time and make my life easier (it's not a must, but I said if I could get both, then why not? -- to make sure my answer is correct for example) though I am not sure what the CAS is capable of on the AFX, I found little to no reviews about it, mainly the stuff I would like in a CAS, are, limits, indefinite integrals and implicit differentiation... but as I said, it's preferred, not a must. It would be nice if you could tell me what is it capable of.

 

About the FX 9860 CAS programs, what are they capable of? I can't seem to install it on the EMULATOR, but I'll try, but from what I read, they only have features like expand, simplify, reduce and differentiate

 

I'm really confused right now, I was kind of settled on the AFX... (in my head it was like this. CAS + storing stuff = great), now I dunno.

 

Is there any major difference between the AFX & 9860? (excluding the CAS)

 

EDIT: Note that I will use either calculator just for the exams, I probably won't use it in the future that much. With that in the equation, should I still consider the FX over the AFX?

Some schools ban calculators that have CAS on them.

fx-9860GII doesn't have CAS, but you can install a custom add-in made by kucalc that has CAS, but it doesn't work on the newer fx-9860gII because Casio changed the CPU from SH3 to SH4A a while ago, so all the 9860giis on store shelfs are now SH4A-type calculators.

 

Fx 2.0 is really old now, and it doesn't have much custom programs, which isn't a big deal if you're not going to use it much in the future.

CAS add-in Eigenmath should work on both platforms SH3 and SH4

So, overall there isn't much difference between AFX's CAS and Eigenmath's ported CAS in 9860, right? Eigen CAS has no limit calculations though

I ran the program but there's no syntax at all, how do I know the features of this program without having to go back to the manual everytime? I'll now buy the 9860 as I see no major difference in the CAS after I installed Eigenmath

 

Btw, I saw different versions of Eigenmath on that site, which one is best and user friendly? I can't understand a thing :(

 

Thanks! (sorry if I keep asking a lot of questions!)
