Symbolix CAS for fx-9860G/fx-9860SD/fx-9860Slim/Graph85/Graph85SD
New Version!!! - v0.4

It doesn't slice and dice, rather... It factors and expands! A valuable tool for highschool mathematic students. Symbolix provides the fx-9860 user with algebraic and symbolic manipulation tools at their fingertips. It's still in the early stages of development, but more to come soon!

* Simplification
* Polynomial expansion
* Polynomial factorization (rational factors)
* Factor quadratics (using quadratic equation)
* Collect coefficient
* Substitution
* Common factoring
* Differentiation

Wow! Thank you kucalc, I was waiting for this since you released that first version of your CAS. A lot of people told me that a CAS would really help in my exams, lets see . Now I'll try to figure out how it works.
The download link is broken, can you fix it?
Keep the good work.

I've released v0.4 Beta of SYMBOLIX CAS. Check out the file sharing to download it.

Remember, it's still Beta, so I know there are still some problems with it. The differentiator doesn't support inverse trigonometric functions. I'm considering removing cubic and replacing it maybe with a command for integration or limits. cubic is just too memory intensive. Well, see... The final release of v0.4 should contain the fixes. But the Beta, should give you a feel of how progress is coming along for SYMBOLIX.

You'll see that v0.4 is a big improvement over v0.3. For example, try to find the derivative of (x^3+5x^2+2)(3x-10) with SYMBOLIX and you'll see what I mean.

For v0.5, do you guys like 3D?

Hello Tom, thanks for trying out SYMBOLIX.

If you read the manual, commands don't require a closing parentheses. This helps SYMBOLIX distinguish commands from functions.

So polydiv actually does work:

polydiv(x^2-y^2,x-y
>x+1

The factoring seems to be my error, not SYMBOLIX's. As a last minute change before releasing the beta, double negatives "--" were suppose to turn into positives. Instead, I had it programmed to trim away a negative sign, leaving one negative sign. That'll be easily fixed in the final release. As for prime, it's intended to prime factorize an integer, not an expression. The expression could be easily simplified into an integer before using prime just by typing 2^2*4^4 getting you 1024.

Thanks barnaby for your tests. It's nice to see tests of Symbolix running on the fx-9860Slim.

I've released a new version contain bug fixes and new features. You'll find a new version in the FileShare.

Added:
+ Common factoring
+ Substitution
+ Support for inverse trigonometric functions in the differentiator
+ Simplify radicals (360^0.5 -> 6*10^0.5)

Removed:
- Cubic factorization

New features being planned for v0.5:
* 3D graphing
* Integration
* GCD and LCM


PS: I've renamed SYMBOLIX to just Symbolix. I've been getting emails about what the letters in SYMBOLIX stand for. They don't stand for anything. I just thought it looked cool with the letters uppercase, but to prevent confusion it's just now Symbolix.

Sorry for not logging in...I'm at a hotel typing this on an unsecured network so I dont trust it But any ways I have a very quick way to find the LCM of any number of numbers...find the GCF of the numbers and then A*B*C....\ <Greatest Common Factor> = LCM -- I created a BASIC app on my calc for 2 number and three number LCMs and it works really fast and doesnt have any errors (none that Ive found anyways)

Congratulations for you ADDin symbolix kukalc !!
I have a very big trouble with symbolix addin, when I run it screen shows this error:

System ERROR
REBOOT   : [EXIT ]
INITIALIALIZE:[EXE]
 TLB ERROR!!
 TARGET=000000
PC =0000000

I press exe and exit but the result is the same: nothing happens, it returns to the main menu. I don't know what to do.
I reset calculator but the same thing occurs.
I have SO 01.03.000 in fx-9860G SD, if you can help me ??!!

Another thing I ask to you is about programming CAS with lisp. I'd like to make some program with symbolic elements in C, but i don't find a good program to translate from lisp to c code. Thanks for your programs

Ok, so you got the addin to run successfully now?

Yeah, you can't use Visual C++ libraries with the CASIO fx-9860G SDK. Some matrix operations in Symbolix isn't such a bad idea...

Hey kucalc , fantastic work Your program was the first I put on my new 9860g . Jus wondering if you will do a new release soon , maybe add partial differentiation and fix some bugs like dy/dx(x^1/3) which crashes . Cheers

Thanks for using Symbolix guys!

Unfortunately, Symbolix is no longer being developed for the fx-9860G platform. The fx-9860G is just too crappy for Symbolix to run in. Yeah, I know it could be more worse (imagine Symbolix on a TI-84!!! ), but... Symbolix is memory hungry and the fx-9860G just can't provide that. When the heap memory gets full, the fx-9860 just fails and crashes.

You may Symbolix again in the future, but it won't run on the fx-9860G, instead on a better platform.

symbolix is being abondoned for the 9860 yeah?

Bloody hell, how's it that CASIO's CAS manages to run in an FX1 then? Magic is it?
I don't know (and probably won't) exactly which algorithms for parsers, lexical Math analysis and actual CAS are you using, but without further nicety I can say that they are plain inefficient, perhaps you ought to change them.

I find it sad to see you so frustrated with 9860 kucalc in a short period, I've seen you more and more irritated with the machine, what's going on?

@ LordNps

I think AFX's had 144 Kb on user ram (and the RAM chip is a 256K i think).
years ago when i was a "9860 is a crap" supporter i saw that many people said that the 9860 system RAM is almost 512Kb based on the chip specs. Is that true??.
AFX was programmed at the core on the good ol' days using weird things as assembler, for sure those guys did make a memory management system that fit their needs, as when you do grayscales and such.

I think that the 9860 was a step backwards on the casio line, isn't it supposed to be better than the AFX series? (in all aspects, not only far greater speed).
If they wanted a calculator for the school, an upgraded 9850 series is far enough to do the job. in fact, i think that more than a 570 ES on school is too much horsepower.
So they put a SD slot ("pro" feature) on a CAS-less and RAM-less calc without doing a newly revamped OS (as Classpad OS is)

Casio must release a "keyed" version of the classpad with a high res screen, Classpad's O.S and more RAM. I see the CP as the most powerful calc to date. And it will be at least when Nspires get serious programming abilities (i don't know if that's already done).

"offtopicking" end.
PS: sorry for the new nonexistant words

Are you saying someone hired you from Casio to develop and extend the Symbolix under their name ? Or maybe they want it stopped and they are paying you money to cease development . I am confused....
