and taylor with several variables

[Overlord]

seems that there are problems with equations involving modulus :

solve |z|=1 in C : z=-1 or z=1, but you have infinite solutions... (like z=i, z=-1, ... all z=a+bi with a?+b?=1)

[qwerty841]

it does simultaneous graphs already...

how's that?

[betoe]

Only select more than 1 function to graph. Maybe you want to say "dynamic" graphics, like the AFX (i dunno if the classpad do it ).

[qwerty841]

i mean split screen with two separate graph screens.

[CrimsonCasio]

ahh, thats not what i was talking about, im not sure if it can do that.

[Overlord]

ability to differentiate multivariable functions (give the results in a matrix), calculate multivariable limits (especially 2 var)

Is there an alternative LCD protector, because this one really worsens the LCD brightness.

By the way. Is it possible to buy a new original LCD protector, since mine is already scrached a bit

[bren_iii]

here are my following suggestion regarding the casio's classpad
1. The CAS mode should be able to solve integrals involving special functions like the sine integral, cosine integral etc. and evaluation of bessel integrals, gamma functions etc.
2. For vector functions, divergence, curl and laplace should be present. also, the coordinate systems should not be limited to polar, cyclindrical and spherical coordinates. include also the "other coordinates systems" like the parabolic coordinate system etc.
3. For 3D graphing, A graping functions exclusive for Quadric surface will be much appreciated. Like COnics which is isolated from the regular graphing function.
4. Solutions of partial and ordinary differential equation symbolically or numerically.
5. It should also support the Integral transforms like laplace, fourier and Z transform.
6. Likewise for differential equations, the hypergeometric, Bessel, chebyshev DE's should also be included. including the orthogonal polynomials.
7. for statistics, It should also have support for probability distribution like pareto, weibull, gamma etc.
8. for descriptive statistics, it should also have funtions for kurtosis, skewness etc.

i think, with these "added functions" it would be beneficial specially for educators, engineering, research or students. It would ease and support them analyzing Heavy higher math problems using a calculator only.

[betoe]

Nice suggestions, i would like a lot to have Laplace on my classpad; Admins: it would be good add this to the "classpad suggestions" topic.

[CrimsonCasio]

ok, doing that now...

btw, John you can call this number to speak directly with the product replacement parts coordinator at Casio: 973-361-5400 ext. 4141

Hi.
I want to use my ClassPad in my class, but I have taken of the LCD protector, and it is now in "not good" condition ( protector ). Do you know somewhere to give me the LCD protector for free ? It is so hard for me to call to Casio ( and I think it is very cheap ).
Thanks.

[qwerty841]

i'm not the only one who killed their screen protecter

[mazdak]

doing Laplace & Fourier Transforms & Drawing bode diagram (TI and HP do)

[qwerty841]

how about not automatically clearing program output and text file contents when you exit the program application

[Daruosh]

It would be nice if all buit-in applications have a Help menu.
Also Financial Application in inevitable.

John & Lovecasio,

I use a PDA (Palm) screen protector film on my CP, and it's perfect. It is much better than the Casio protector. I have some spares. If you give me your mailing address, I'll send you guys one with application instructions. I'm a nice guy. I'll even pay for the postage. Let me know if you want one.

[CrimsonCasio]

you should post where you get yours, that way people wont have to give out their address to people they dont really know if they feel uncomfortable about it

[Kal Culator]

Crimson,

Sorry, you're right.

In the USA you can get them at any office supply storte where PDAs are sold.

I'm sure John and Lovecasio can buy them at a similar retailer in their respective country.

[betoe]

This isnt much important but I would like the classpad in other colors, coz white need to be cleaned constantly.

I would like another cover for my classpad. I will try on "office depot", i think that maybe they can sell it, also i need another stylus. But some months ago i went to that store and the newest casio calculator they sell here its the AFX 2.0 :S.

[CrimsonCasio]

i know you can get another stylus from that number i posted, thats why I have it in the first place

[John]

Kal Culator, Thanks for the help anyway

[Lovecasio]

Hi.
Thank you so much, Kal Culator. ( so slow because I have not been in the internet for a week ).
To email me, just click my signature.
Thanks again.

[qwerty841]

a couple that my ti v200 has:

xorpict (inverts the pixel on the screen if there is a pixel on in the pict)
rplcpict (replaces what's on the screen with the pict)

[CrimsonCasio]

you know that second one can be done just by doing:

Cls
RclPict (...)

as for the other, i'm all for new programming commands!

[Daruosh]

Does anyone know that how these suggestions will be consider in the next OS version? Laplacian and Fourier Transform are really inevitable.

[CrimsonCasio]

i just know that Casio checks this topic every now and then, i dont really know how it effects what they do next... SoftCalc might know more about the process.

[Andrzej]

I don't know i can be boring asking the same quastion but first suggestions may be not readed by the people from casio so:

What happened with gradient scale (400grd=360dec=2rad)?
Why classpad hasn't got it, when all previous casio calcs, have it???

It can't be hard to fix it, and i just want it updated in new OS, coz I'm doing a lot of calcullus on this scale, without this function i have to recalculate it on other scales, what makes my calculus more complain.

[SoftCalc]

Does anyone know that how these suggestions will be consider in the next OS version?

FYI, I definitely read the forum and your bugs/suggestions . I've also seen an internal bug report quoting it was originally reported on UCF, so someone in Casio must read this forum .

[CrimsonCasio]

really? can you tell us which one it was... it would be interesting to know when we find "original" bugs.

[Daruosh]

FYI, I definitely read the forum and your bugs/suggestions . I've also seen an internal bug report quoting it was originally reported on UCF, so someone in Casio must read this forum  .

Do you know that CP OS development team consider our suggestions?
"Fourier & Laplace Trans and invers of them"???

[SoftCalc]

Do you know that CP OS development team consider our suggestions??

Of course I can't comment on what Casio is currently working on, but I can say Casio is listening.

[Daruosh]

Your news is so HEARTSOME. tnx
Don't forget: "Fourier & Laplace Trans and invers of them"
tnx. tnx, tnx
Realllllyyyyyyy tanx. tnx. tx

[qwerty841]

you know that second one can be done just by doing:

Cls
RclPict (...)

the pixels dissappear before you see them.

maybe i could just turn on or off all pixels that would need to be turned on or off.

[CrimsonCasio]

what do you mean they dissapear? they shouldnt...

[Nanard]

try this:

SetBG Pict1
Cls
SetBG Pict2
Cls

[qwerty841]

how come when you set the image as a background it displays all the pixels at the same time, but when you recall it, it doesn't?

[betoe]

A lot of spanish guys had e-mail me about if there is a financial app. for the classpad (like the one of the AFX). It would be great for all the comunity (not for me ).

Softcalc: do you know something about a financial app?

[Nanard]

how come when you set the image as a background it displays all the pixels at the same time, but when you recall it, it doesn't?

nop, the new image is display when another action is done on the graph screen (as Cls).

[Daruosh]

Shaded 3D Graphs.
Drawing f(x,y,z) = 0 patchs.
Drawing Splines in different orders is nice features.

I'm waiting for new OS and reflection of out suggestions impatiently.
