Group Theory,

Given a Group G and a normal Subgroup H.

I can get " map(Representative,RightCosets(H,G)) ".

Is ist possible to get the factor group  G/N ?

Best regards

Hey, 

I am trying to write a single procedure to find the root of any function using the Newton-Raphson method, given the initial approximation and the tolerance. If this fails to converge, the program must then use the Bisection method to find the root. Need some help please. The current procedure i have done is only coming out with the first Iteration 

Thanks for the help!

hi dears. i cant solve this question by Analytical method such variational itteration method (VIM) or homotopy perturbation method (HPM), homotopy analysis method(HAM)

Hello;

Suppose we have a vector as follows:

Plex:=[u,v,w,x,y,z]

Could anyone help me to reproduce the following vectors via a "for" loop?

[ v, u, w, x, y, z]

 [ w, v, u, x, y, z]

 [ x, w, v, u, y, z]

 [ y, x, w, v, u, z]

I have a simple Matlab script which can do what I intend. So, my question is how can I implement this script in Maple?

Plex=[u,v,w,x,y,z]

for i=2:5

    Plex=[Plex(i) Plex];

    Plex(i+1)=[];

    disp(Plex)

end

Thanks in advance.

how to singularize existing function?

any group theory can describe the singularity function?

Good day, please how can one solve these BVPs using FINITE DIFFERENCE METHOD in maple. Here is the problem FDM.mw

Hi;

Could anyone help me to convert the following codes into Mpale?

while n>= 1
    for i=1:n
        S(i)=resultant(F(i), F(i+1), Plex(i));
    end
    F(i)=S(i);
    n=n-1;
end

Thanks in advance.

Hello! I have written a code to solve 1D heat equation with Neumann B.C. using explicit method. But there is a problem with plot. I don't understant, what's wrong. Help me, please. I will be very grateful. The code is attached here.

Hello,

I am writing a program in C that uses the open maple library. It is not the first time that I use it but now I am facing a strange problem that involves the simplify command: suppose a,x,y are symbols that are not previously used in maple, the following lines

1)  EvalMapleStatement(kv, "simplify((a*x^2-y^2)/(x^2*y^2-1));");

2)  EvalMapleStatement(kv, "simplify((2*x^2-y^2)/(x^2*y^2-1));");

only differ by the fact that the parameter a is replaced by 2 in the second line. But they return the following output:

1) (a*x^2-y^2)/(x^2*y^2-1)

that is correct, nothing to simplify..

2) Error, (in gcd/LinZip) input must be polynomials over the integers

I must be doing something wrong but I am getting nowhere...

Thanks...

P.S. This is the complete listing 

#include <stdio.h>

#include <stdlib.h>

#include "maplec.h"

static void M_DECL textCallBack( void *data, int tag, char *output )

{

    printf("%s\n",output);

}

int main( int argc, char *argv[] )

{

    char err[2048];  /* command input and error string buffers */

    MKernelVector kv;  /* Maple kernel handle */

    MCallBackVectorDesc cb = {  textCallBack,

                                0,   /* errorCallBack not used */

                                0,   /* statusCallBack not used */

                                0,   /* readLineCallBack not used */

                                0,   /* redirectCallBack not used */

                                0,   /* streamCallBack not used */

                                0,   /* queryInterrupt not used */

                                0    /* callBackCallBack not used */

                            };

    ALGEB r, l;  /* Maple data-structures */

        char *myargv[]={"maple"};

        int myargc=1;

    if( (kv=StartMaple(myargc,myargv,&cb,NULL,NULL,err)) == NULL ) {

        printf("Fatal error, %s\n",err);

        return( 1 );

    }

EvalMapleStatement(kv, "simplify((a*x^2-y^2)/(x^2*y^2-1));");

EvalMapleStatement(kv, "simplify((2*x^2-y^2)/(x^2*y^2-1));");

    StopMaple(kv);

    return( 0 );

}

Is it possible to numerically calculate  the integral

int((-12*y^2+1)*ln(abs(Zeta(x+I*y)))/(4*y^2+1)^3, [y = 0 .. infinity, x = 1/2 .. infinity])

in Maple?

The code

int((-12*y^2+1)*ln(abs(Zeta(x+I*y)))/(4*y^2+1)^3, [y = 0 .. infinity, x = 1/2 .. infinity],numeric,epsilon=0.1)

has been executed on my comp  without any output since this morning.

Hello everybody, i need to graphic a couple of functions just like this one:

 http://temasmatematicos.uniandes.edu.co/Casquetes_cilindricos/Pags/Anim_1.htm

i have been watching this:

 http://www.maplesoft.com/teachingconcepts/detail.aspx?cid=12 VISUALIZATION --> Animation 2

i've tried with (plots) (plottools) animate, etc. but i can't figure out how to do it. 

It would be very helpful if someone explain me how to do this.

Thank you all!

I have setup two groups in MapleCloud, to be used for distribution of materials (a readonly group) and as a drop for students to deposit their exercise sheets (an opaque group). It is my understanding that e.g. students have to request joining a group and I get to approve them.

How does one join a group managed by someone else? If I try from another account I cannot see the groups I just created, so I cannot request joining them. I seem also to not be able to just approve someone (by their email e.g.) without that person having requested to join first.

???

Thanks

Is there a way of ploting y=x^x for when x<0 and y is a noncomplex solution?
