Re: Gauss-Jordan reduction

Welcome to the forum somebody1234. Thank you for joining us. If you are working with ClassPad you can store the matrix to a variable name. In fx9860g and fx-cg the matrix should be saved under matrix memory Mat [A-Z]. Exemple: In fx9860g/fx-cg: [[1,2,3],[4,5,6],[7,8,9]]→Mat A In Classpad: [[1,2,3],[...

Chemical equation balancer... from Classpad basic to the web

In September, I released the BCEB (basic chemical equation balancer) for fx-cp400. Since the Classpad basic is a bit limited (no regex, no functions, is slow) I reached a point where becomes difficult to continue to improve the program, with version 0.3. Recently I decided to continue with the devel...

Re: FX-CP400 Bug in LU

is there any place where there is more information and toturiais video? There is Classpad101 site with some pdf guides explain the functions of the previous b&w models. I think that even being done to an older model, is easy to understand. The fx-cp400 manual also helps to understand some comma...

Re: variation table of a function

I tested the program on fx9860GII and it seems that there are some problems with SolveN function. The calculator does not seem to be able to solve d/dx(x^3-x) for exemple, contrary to Prizm. However calculating the derived equation manually, gives the correct result. https://i.imgur.com/ThLqhGN.jpg ...

Re: CPeriodic - Periodic Table for Classpad 400

Is normal the little "loading" indicator keep spinning. This means that the program is running and waiting to get the pen coordinates. I tried to do my best when I created/updated this program and I think I can not improve more than the current 2.00 version, in terms of speed. If I am righ...

Re: variation table of a function

I saved it as *.g2m format (and I think that it doesnt use any fx-cg20 basic exclusive command) , so should be compatible with fx9860gII without any change. My emulator has expired and I do not have this calculator here, so I can not test currently. The program can show some roots in exact value, li...

Re: Fun Tutorial for Casio Basic

I'm trying this out in the Classpad software, not in the calculator it self. This tutorial was written to the fx9860 (and fx-cg20). The classpad basic language is a bit different. The second exemple in cp basic should be: Lbl ONE GetKey A Locate 1,1,A Goto ONE In classpad, the lbl parameter <name> ...

Re: variation table of a function

I tried and managed to make a program to do this, in basic. I used the command SolveN( to find the roots of the derivate equation that the user write, so it only will display up to 10 zeros, even if the function has more (like trig functions for exemple). I think it is working properly, however, onl...

Re: Problems with file copying function

Inside LCDR61524A.dll is the text "LCD driver R61524 with touch for CASIO" plus some other touch references. So the touch controller seems to be an integral part of the R61524. One curious thing I've seen in cncalc is that some ex-word dictionaries have the same screen size and resolution...
