Is there any fully working CAS for fx-9860GII? By that i mean it can differentiate and integrate. All the ones i can find can only seems to differentiate.

[Karan901]

/bump ? how to create one?

[scientifix]

you should test the CAS on jeuxcasio

http://cas.jeuxcasio...en/download.php

[Karan901]

I have tried this one but it only lets me differentiate? which bring me to my original question... :/

[Casimo]

What about symbolix?

[Karan901]

Same thing, i have tried both but Jeux does not support differentiation and symbolix project was abandoned leaving integration not completed. Therefore i wanted to know if i can do it myself? How? or if anyone can help.

[Casimo]

You should learn C(++) first.

[Karan901]

Well that would take me forever, then trying to write the program even longer... Anyone willing to do it if i pay them

[Casimo]

At the moment i'm busy. But let me see whether I can understand what I have to do and maybe I could write a program later.

[Karan901]

Thanks a lot.

[Casimo]

Wait, that seems to be extrem difficult. I'll look for an existing program and try to port it (not now, no time).

[Karan901]

I understand you have more important things, this is just something i'm curious about. So if you get time to check it out great but otherwise no worries.

[scientifix]

Karan901, CAS jeuxcasio is also integrating, its not written on the download page but it is doing it !
I have it on my calculator it's in the calc menu
have a nice day

[Casimo]

What about differntiating?

[Karan901]

Diffrentiation works fine, but i can take a photo if it will help? If i write X^2 and try to integrate it all you get is "Error : syntax". The answer shown should be X^3/3, but clearly it does not work, and i don't have the SD version of the calc either.

enter integr without anything inside :integr( and clic EXE it will tell you how to enter the integration, it is woking !!

[scientifix]

you also have to enter the variable : integr(x^2,x and it will give you x^3/3

intgr(x^2) gives me an error...

[Casimo]

So, am I wrong or is the CAS program Karan901 wanted to have not needed anymore?

[flyingfisch]

I think it is still needed.

[scientifix]

YOU HAVE TO ENTER :
intgr(x^2,x and it xill give you x^3/3

[Karan901]

So this is very basic right? Since it can't seem to give an answer for sin(x) or ln(x).

[flyingfisch]

YOU HAVE TO ENTER :
intgr(x^2,x and it xill give you x^3/3

Oh ok I see now. Thank you

[Casimo]

So my program hasn't to be made? xD

[Karan901]

So does integrating sin(x) or ln(x) work? By that i mean do i have to enter something else. i.e for x^2,x.... so for sin(x), ???.

Is there a way to do it like above or does it not do that?

[scientifix]

sin(x),x after the "," you have to put the variable (x or y or a or b ...)

[Karan901]

This results in another message coming up, " No exact solution found". I have put in 'intgr(sin(x),x)' and i have got that message. The answer should be -cos(x), but no matter how i try to input the (,x) at the end i can't get any answer (let alone the right one).

[flyingfisch]

Is this project helpful at all? http://www.casiopeia...t=1336&start=30

[scientifix]

Hi everyone,
I found this (I'm sorry its french but you'll find parts of the source code of the Xcas CAS) can somme one see if I it would be possible to make an add in with those code ?
