Can I draw "y=sin(x) , -2pi<x<2pi" to CP300 ? How ?

[Overlord]

i don't understand the end of your message

[2072]

well I corrected the end of his post, the "<"sign did not passed...

[Lovecasio]

Hi PJ.
You can try this:
From Menu, tap Graph&Table.
In y1 line, input: piecewise(-2pi < x < 2pi, sin(x), 0)

Then tap button to draw. It will appeare the graph of y=sin(x) within your range, although it will take more time.

[PJay]

Thank You !
and can I get : " Df " , " Rf " for "y=x^2" with CP300 ?

[Lovecasio]

What is Df and Rf ?

[PJay]

What is Df and Rf ?

For example : If : f(x)=y=x^2+1 , Then : Rf = 1≤x<+∞ and Df = -∞

[maurice1979]

He wants to know if he draw a graph of function y=sin(x) between -2pi and 2 pi
, I don't know hadn't tried it oot.
BTW
Is it possible to change yoyr axis values?

[CrimsonCasio]

you should be able to do that in the view window options (scale, dot, etc...)

[PJay]

Can you explain it more ?

[CrimsonCasio]

sorry, I wasnt refering to you, I was answering the question about changing the axis values.

[PJay]

Mean CP300 is impotent about this case ?

[Lovecasio]

I am sorry, PJ. I still dont understand it. It would be great if you explain more. May be I have not studied about Rf and Df yet. Can you write it ( Df and Rf ) in complete words?

[coco]

Df stands for Domain of Function which is the set of allowable values that the independent variable (usually 'x' in a two var function) can take.

Rf stands for Range of Function which is the set of values that the dependant variable (usually 'y') can take.

Hope it helps

Hope it helps

but now, how do you input f(x) = x^2 Df [-2,0]??

[huhn_m]

thats how it works on the (A)FX/CFX

Y1= X^2,[-2,0]

thats it! try it

[CrimsonCasio]

That gives me a sentax error...

[UserC300]

Y1= X^2,[-2,0]
That doesn`t work.
Well, it says in the manuel(German, Chapter 2-4-11) that you should be able to do it with the "with"-Operator(|).
Like: y=sin(x)|-2pi or y=sin(x)|-2pi But it doesn`t work(Buck?), you can just type in one Option for x.
y=sin(x)|-2pi

[UserC300]

The rest of the message before got cut off.
y=sin(x)|-2pi is working!

[UserC300]

OK, sorry for taking so much space.

Here the solution:

y=sin(x)|-2Pi<x|2Pi>x

That works! Hope somebody is still interested.

[CrimsonCasio]

yeah, thats great to know. thanks.

[maurice1979]

Me too.
I only have it for about a week, and it take more than a week to learn to use it to it's fullest.
Anybody know some usefull tutorials??
I ones found one but didn't bookmark it and i can't check history, 'cause it wasn't my pc. What I found had animated gifs that show how to do things, quite usefull. Couldn't find that in the manual.

maybe the should add a few hundred more pages.

[betoe]

Well i dont remember well but one time i download a basic and good CP tutorial, its a power point document. I think that i download that file from a french site. If you want it e-mail me and i will send you, but one thing: via hotmail i can send only 1MB . If you use AIM or MSN add me to your contact list and i will send the file to you.

[maurice1979]

Is it in french?
cuz, my french is real bad, my german is even better...
ok i'll give you a mail, it can hold a few MB's .

[betoe]

English document, but with good examples.

:/ I don't think it'll fit into a floppy... <_<

looks like I'll have to visit a someone with a cd-burner and fast internet
i'll go have a look see.

[UserC300]

This is a Link to the german Casio-Support for Graphic-Calculators.
Casio-Support.de
They have some hints, for example:

Hinweise: Da der ClassPad 300 bei Verbindung mit einem PC ?ber den USB Port die notwendige Leistung ?berwiegend ?ber den USB Port bezieht, kann man somit eine longere Batterielebensdauer erreichen, wenn bei Betrieb vom ClassPad das USB Kabel am PC angeschlossen ist. Sie brauchen dabei einfach das Kabel anzuschlie?en, eine Verbindung ?ber das Programm ClassPad Manager ist nicht notwendig.

They say, that the Classpad gets most of the power over the USB Port when conected, saves batteries.

[Lovecasio]

Can someone explain the "Save power mode" ? What is it benefit (I read it in the manual but I still dont understand).
Oh PJ, I afraid that ClassPad cannot do Rf and Df.

[CrimsonCasio]

powersave happens when you dont use the classpad for an amount of time (you can set it), when it happens it will shut the classpad donw compleatly and you will need to recalabrate the pen and set the contrast (etc...), if you were in an application you will have exited it and will be in the main menu, the advantage is that the classpad's batteries will last longer.

[UserC300]

In Powersave-Mode, Classpad saves everything to the FlashROM wich needs no power to store the data.
Never had that:"recalabrate the pen and set the contrast (etc...)" after Powersave.
Mine shows two pictures(Classpad now loading) and then shows the Menu.

[Lovecasio]

Thanks. I understand

[UserC300]

Do you know, if there is an Casio-Basic Reference available beside the Cp300-Manual?
What Command is the replacment for
a=b=>c ?

[CrimsonCasio]

in my off time I'm making a e-activity on programming basic, the replacement for that is:

If a=b
Then
c
EndIf

[UserC300]

Ja, I thought so. I find it a bit to complicated for this little testing. They should have kept the old one.
An e-Activity for Basic-Reference would be great!

[Andy.Davies]

do u wanna make one for ASM/C aswell?

[UserC300]

Is there a way to find out if a Variable is defined?
Like:
If A=Undefined/Defined (or A[8,6]=Undefined/Defined)
Then
...
...
...
IfEnd

[CrimsonCasio]

use get type:

GetType Var,Res
StrComp Res,"NONE",isdef
if isdef=0
Then
Print "Not Defined"
EndIf

[betoe]

Well i think its the better topic to post this question:

Can i use the CAS mode in a casiobasic program (coco made me this question on the spanish forum but i dont know the answer, i think no...)?
