guys, i put a test solution in my differential equation and when i excuted it, maple calculated the solution in term of functions itself. 

i mean, i have functions A(r),B(r),C(r),phi(r) in a differential equation and then i put A(r)=(1-a/r)^alpha and B(r)=(1-a/r)^beta and C(r)=(1-a/r)^gamma and phi(r)=Q*(1-a/r)^lambda , maple give me result with A and B and ... . i want to maple give the result with out any function and just in term of (1-a/r)^... and alpha , betta , .... and c

and is there any way to arrange in term of power of (1-a/r)^... or something like that ?

what is your opnion ?

and also i obtained the differential equation by maple and it is not simplify completely and some terms can cancel each other how can i simplify it completely?

thanks in advance

Could you print A & F ?

Hello i would love some help with this code i need Maple to make an exercise guide in word automaticly the thing is that i don't know how to automaticly insert the plot in the word, i think there is no fprintf format to add images or plots maybe with exportplot? i really don't know; here is the Code is Basic for a starter student i just need the comand to insert the plot just that.
-------------------------------------------------------------------
fd:fopen("Graphs.doc", WRITE);
 for i from 1 by 5 to 11do
  if i=1 then plotsetup(bmp,plotoutput=plot1);
 a:= -50;
 b:=30;
 elif i=6 then
 plotsetup(bmp,plotoutput=plot2);
 a:= 50;
 b:=-30;
  elif i=11 then  plotsetup(bmp,plotoutput=plot3);
  a:= 2;
 b:=-3;
 end if;
 h:=(i*x^(2)-((3*a)/(i-42))*x-(i*b)/(-i+42));
  fprintf(fd,"the quadratic equation is: ")
fprintf(fd,"%q \\n",h);
 #`HERE IS WHERE I NEED THE PLOT TO BE`
  plot(i*x^(2)-((3*a)/(i-42))*x-(i*b)/(-i+42),x)
   end do; 
 fclose(fd);
--------------------------------------------------------------------
pd. i can't do it manually i need it to be automatic later i will add some inputs to make it even faster.

Hi, as I can't manage to copy and paste on mapleprimes, I would be glad to get a hint ...

Hello,
I am looking here for a tutor, that can help me doing some Maple V (5) programming.
I am a mathematic student and we use Maple programming.
I will be happy to pay a small amount of money for each exercice you help me doing,

if anyone is interested, please contact me here.

(The procedures that we usually have to write are for example:
 Newton-Raphson Method, Chebyshev Polynomial,...  I don't think it is hard for you.
Thank you very time for your time and your help.

Hello,

I would like to export maple inputs as xml code. The aim is to recover the semantics of the inputs.

I have tried without success with the Export Function.

Have you some ideas to export maple inputs as xml and with preserving the semantics of the input ?

Thanks a lot for your help

Maple function plot allows to build a linear plot for two vectors, when one vector contains X coordinates, another -- Y coordinates (similar to plot below):

Is it possible to build such a plot for several Y-vectors like this:

I want to solve the following differential equation

solve(y''(x)=(λ*x* y[x])/Sqrt(-1+ x), y(x),x)

But do not know how to actually solve it. Any suggestion?

I'll be vacationing in Amsterdam May 1-11. I was wondering if there are any Maple-related activities or institutions there that I might visit. I believe that the Netherlands has somewhat of a national drive toward the use of computer algebra in education, much more so than the United States. Can anyone here confirm that? And if that's true, is Maple a big part of it?

I'm new to mapleprimers and if I make some mistakes I apologize. 

The problem I ran and on which I ask for help is that the command of maple latex I results in latex only the result of an arithmetic expression and the expression does not translate into latex itself. for example, the command latex (3 + 2) I 5 and not as a result from the translation in latex of 3 + 2. I also tried using the command inetrt form but did not succeed, I tried it with the quotes '' and even succeed. I also tried it with double quotes and with simple expressions funzioa eg latex ("(3 + 2) * 5") from me as a result `` (3 + 2) * 5 '' but with more complex expressions: eg. latex("\""(2+1/(5))^(0)+(6/(9)*(((83-8)/(90))-15/(10)+(3/(9))/(2)) -6/(9))/(75/(100)*12/(9))"''") mi da
