Hello,
I don't quite understand what you mean by expand a problem. The expand( command is used to develop expressions such as (ax+b)^2.
For this expression the calculator will give a^2.x^2+2.a.b.x+b^2, which is the correct answer. The dots stand for the multiplication sign.
If you tell us what you are trying to do, we might be able to advise you better.
Hope it helps.

Phasor addition on classpad 330


Open up keyboard, go to 'cat' tab and scroll down to get ' <( ' symbol.

Input the magnitude followed by angle separated by a comma (E.g. <(15,10) ). The first element in the bracket is the magnitude of the phasor while the second element is the angle.

To do phasor addition simply add more of the '<(' symbol. (E.g. <(15,10) + <(12,5) is the addition of phasor_1 with magnitude 15 and angle 10 and phasor_2 with magnitude 12 and angle 5 ).

Note: the symbol ' <( ' appears at the very bottom of the list and the '<' symbol is actually more flat in appearance like how a normal phasor is usually represented.

Instalador de class pad 330 para 64 bits


You do not need any driver for the ClassPad 330. You connect it through the USB port. If it came with the ClassPad manager 32 bits application, just install it. Windows 64 bits system have a 32 bits subsystem to run 32 bit applications.

Here is a screen capture that may help you. Variable must be x. Be careful what type of brackets you use to enclose the arguments. use the ones that are on the same line as Pi, theta, i.

My Casio classpad won't give me the correct answer


I am not sure about what you want. The expression is in its most compact form. So I am assuming you want to exapnd it. The command for that is exapnd( . Just type it using the keyboard or look for it under the Action>Transformation menu.
expand((x+5)^6) [EXE]

Here is a screen capture of what you should get. Notice that I cleared all 1-letter variables to erase any value stored in x.

Whenever the command expand, diff or integrate are use it comes up with wrong argument. I have tried to clear all variables and default the set up but to no avail.


I believe you are using the wrong syntax for the commands.
diff ( function, variable) Example: diff (sin(x^2), x) sgould give you 2.x.cos(x^2)
expand( will expand an expression that has parentheses: expand( (a+b)^2) will give a^2+2a.b+b^2
Integrate $
$ ( tan^-1(x), x) willl give x.tan^-1(x) -(1/2) ln ('x^2+1')

Check the syntax of a command before using it. You will find the list of all comands and their syntax in the reference manual.

How do I enter degrees minutes seconds on casio classpad 330


This is valid for the ClassPad 300Plus (OS version 2.2) but it should work for the ClassPad 330 OS version 3.x

In the MAIN menu screen press the Action menu, then Transformation sub menu. At the bottom of the drop down list you have dms an toDMS.
If you enter toDMS(18.58) you get dms(18,34,48). Then if you use dms( on the calculated result: dms(ans) you get 18.58
So if you have a result in deg, min, sec you convert it to decimal degrees by making use of the dms( command.

Can you update a classpad 300 to a 330 operating system


It depends. If the ClassPad has OS 1.x you can upgrade it to 2.x freely. However you need to buy (separately) the ClassPad manager 3.x to be able to upgrade the OS to version 3.x. After that further upgrades appear to be free.
