hi everybody,
Could someone make an add in for fx9860gII that can graph and calculate differential equations like on the Algebra FX2.0 ?
It would be great and the fx9860gII would be as powerful as the Algebra FX2.0 !!
I hope someone will make this add in (i dont know how maka an add in)
thanks

Could someone make this add in (differential equation, like on the Algebra FX2.0) for fx9860gII ?
It would be great !

Making a CAS is a difficult and log-term project. If you want someone to do it, you have to be patient. I remember seeing XtrmCas on Casiopeia, if that has what you want, then ask the author of that program about it.

No I mean an Add in that can graph and calculate differential equation like "DIFF EQU" on the Algebra FX2.0

Plotting differential equations can be done with (and actually is) a numeric algorithm. No need to cas. Just an expression evaluator should be enough.

Vanhoa made one for the ClassPad which is open source: http://community.cas...uation-grapher/ (Note: I didn't check myself but read post #13 by PAP which says that program has bugs). PAP has also made one in CPLua but has not released it yet

Anyway algorithms for this are available; but implementations should be carefully tested to make sure algorithm/program is correct.

Hi Micropro,
thanks for your answer !
In which language was this cp300 add in written ? Is it possible to port it to fx9860gII ?
can you give me the names of the available algorithms and where to download them ?
thanks

Is this program good for differential equation ?

Part 1:

"A"? ->A
"B"? ->B
"V"? ->V
"W"? ->W
"H"? ->H
"N"? ->N
SEQ(X,X,0,N,1) ->List 1
SEQ(0,X,0,N,1) ->List 2
SEQ(0,X,0,N,1) ->List 3
V ->List 2 <img src='/dot/public/style_emoticons/<#EMO_DIR#>/1.jpg' class='bbc_emoticon' alt='[1]' />
W ->List 3 <img src='/dot/public/style_emoticons/<#EMO_DIR#>/1.jpg' class='bbc_emoticon' alt='[1]' />
FOR 1 ->I TO N
List 2[I]+ H L->ist 2[I+1]
A*List 3 [I]+B-> F
List 3[I] + H*F ->List 3[I+1]
NEXT
