I am sorry , but what do you mean by "CAS mode", and in what Casiobasic (AFX or ClassPad) ? :unsure:

Computer Algebra System :P , i want to know if i can use Sums, etc... in a program. For classpad casiobasic of course.

    CP300, Fx8.... fraction sumtin', old thing with dust, it still works, with the original battery

Posted 21 November 2003 - 08:29 AM

I have a question about calculating the length of a vector, so far, I used list calculations, sumtin' like:
sum({1,2,3,}^2) then |/? (ans) gives me the length.
Is there a shorcut??

I don't know if there's much of a shortcut..

You could, for starters, sqrt the whole expression (putting it before the 'sum(' )
You could also write your own function to retrieve the length of a vector
If you don't like using 'sum(', you can dotprod the vector with itself, and take the sqrt of that :P

How do I do that?
:blink: It looks kinda complicated :blink:

(example 3-Dim)

For 2-dim just use the complex function compToPol(just ignor the e, the exponent is the angle)

x+y*i

for 2d vectors it's easier to use the Abs() function, f.eks: length of (2,3) -> Abs(2+3i)


alternatively you can define a function that takes any vector (as a list variable):

define len(v)=sum(v^2)^.5

for using it:

len({1,1,1})
(would give sqrt(3))

Abs() is not working(?) and you don`t get the angle.

As I know, the touchscreen technologies are:

-Resistive
-Capacitive
-Surface acoustic wave

What is the ClassPad touchscreen technology do you think ? :lol:



(Sorry because of my disturb)

Sorry, that was 'abs()', with a non-capital 'a'

you use 'abs()' to get the length (or the absolute value) of a complex number
you use 'arg()' to abtain the angle

if you don't see how this fits in with vectors, read up on complex numbers

Userdefined-Function

Is it possible yo use excisting functions within the function you want to create??

for instance: define vlength((sqrt sum({x,y,z}^2,{a,b,c}^2)))

define vlength((sqrt sum({x,y,z}^2,{a,b,c}^2)))


Interesting!?

This is the Syntax for creating a user-defined-function:
Define  [<folder name>\ ]<function name>([<variable name>[,<variable name>...]])  =<expression>


Well, I do not really understand what you want to do, but if the Syntax is correct you can use the CP-functions + user-defined-functions(not the same one).

A user-defined function cannot contain any command.
A user-defined function can contain only a single mathematical expression.

Why don`t you try it(or look it up in the manual)?

Are you referring to casio basic commands?

A function must be such that it evaluates to a value or an algebraic result. Therefor it cannot include any loop constructs, conditional statements or commands. It could use a series of other functions in its expression though..

The function definitions on the classpad are not really functions as such (in programming terms a function would describe an algorithm), but simply a definition of a mathematical expression (which could include functions(built in; real ones, and simple; user defined ones))

I got that directly out of the manual:"A user-defined function cannot contain any command"(12-5-2). Since +,-,/,^,... are also listed(apendix alpha-8-5) as an command(Cmd) and being a bit over-meticulous, it is not really correct. :D

But yes, a user-defined function cannot contain any program-command.

An amazing thing is the ClassPad emulator I download in the Internet at
www.classpad.de, the function (make by program application) can contain Loop command, control command ( like If then else, Do, lpwhile...).

it doesnt save the function when you do that though, if you open it back up its blank.

That does not work. I can`t even save a program-command containing function, made with the Program-Editor.

Although you cannot save the function in the manager that is downloaded in the Internet, but it did work. (So far, you cannot save any thing on that manager).
For example , lets make function gt (for factorial)
-Enter program loader.
-New files: Library folder, name: gt, parameter:n.
Function program:
Local p,i
1->p
For 1->i to n
p*i->p
Next

Then, enter Main and input gt(5), the result is 120 (=5!). I am sure.

Note: It is not the manager come with classpad, it is on the site that I write above.

You are right! It doesn`t work with the CP-Manger-Limited which comes with the ClassPad. With the Demo-Version it works like you`ve described.
They should implement that in an OS-Update. It would be best, and it was already mentioned somewere, if you could start any kind of program out of the Main-Application.

Pluss you should have a return statement with an argument, so you don't have to manually put the result in the Ans var. I think the Ans variable should be saved across function calls so you can use it in your expressions (that might consist of several function calls)

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

Yes, Now can I CP300 get Df and Rf ? :hammer: :(

To the best of my knowledge, now the ClassPad cannot do it. And as far as I know, no calculator can do it.
