Hello,I just can't find out whether it's possible to plot the x-axis 'below' the graph? Normally speaking the x-axis is plotted at y=0, but I want my x-axis to be plotted for example at y=-5 or y=-10. Can that be done?Greetings,Frank

Why does maple not simplify this expression any further:

-4*cos((1/5)*Pi)*m^3-4*cos((1/5)*Pi)*n^3-4*cos((1/5)*Pi)*p^3-4*cos((1/5)*Pi)*q^3+4*cos((2/5)*Pi)*m^3+4*cos((2/5)*Pi)*n^3+4*cos((2/5)*Pi)*p^3+4*cos((2/5)*Pi)*q^3-10*cos((1/5)*Pi)*p*q^2+10*cos((2/5)*Pi)*m^2*n+12*cos((2/5)*Pi)*m^2*p+12*cos((2/5)*Pi)*m^2*q+12*cos((2/5)*Pi)*m*n^2+10*cos((2/5)*Pi)*m*p^2+12*cos((2/5)*Pi)*m*q^2+12*cos((2/5)*Pi)*n^2*p+10*cos((2/5)*Pi)*n^2*q+12*cos((2/5)*Pi)*n*p^2+12*cos((2/5)*Pi)*n*q^2+12*cos((2/5...

with(PIR):
RPP:='PIR/homalg';

'homalg/default':=RPP;

test1 := (3*f-f^2)*(Diff(g, x))+(-f+3*f^2-2)*(Diff(g, y))+(2-f^2)*(Diff(g, z));

test1r := solve(test1=0,f);

 

how to solve this in terms of Diff(g,x), Diff(g,y) etc.

after solve, it is like a bug, because result is Diff(1,x) etc where is g?

 

Hi,

Say for a 126 by 18 symbolic matrix, substituting numerical values into the matrix DD1 takes about 10 seconds (using time() );

for a 62 by 16 matrix, take just about 1/5 second.

By when the matrix is about 254 by 20, it take much longer! More than a minute!

I never actually waited how long, but I am wondering if there is something wrong? Am I using the right command?

Say the matrix is DD1 with numpar:=[x=0.3,y=0.2,z=0.98,....]

HI, I have a doubt to how to execute the program with an example. gaussseidel:= proc (A,b,x,p)  local i, j, m, soma, e, g, C,   xk:= Vector(n),  k:=0;  for i from 1 to n do   g[i]:= b[i]/a[i,i];  for j from 1 to n do   if i=j then     C[i,j]:= 0;  else   C[i,j]:= - a[i,j]/a[i,i];  end if;  end do;  end do ;  while  (x - x0) > p do  for i from 1 to n do   soma:=...

I'm really struggling to do some linear algebra over Galois fields in Maple with LinearAlgebra package. I looked at the documentation for LinearAlgebra[Nodular] and LinearAlgebra[Generic], but i failed to get even simple examples to work. For instance as simple example over GF(2) I tried the following code which in my understanding should return the vector [1,1,1], instead this however simply no result seemt to be computed:

restart;
#with(LinearAlgebra[Generic]):

How can I install package "gravitational" for system Win7 (maple 15 and maple16)?

I made 3 years ago a SOKOBAN game using Maple for my Math/Programming class.

Here is a video of the application:

Have a nice day!

I am trying to shade the area under an arc between it and the x-axis but I can't get it to work. I have used "filled=true". According to my interpretation of the plot tools help page it should work. Any suggestions. Thanks much!

How do i solve this PDE with initial and boundary condition

1. δθ/δζ = δ^2θ/δy^2

At y=0, δθ/δy=0

At y=1, δθ/δy=-µ

At ζ=0, θ=1

Dear Maple users

The Statistics package contain a Histogram command which can produce a linegraph (or what you call it). Ex:

 

with(Statistics):

A:=[3,5,7,2,11,2,1,10,6,15]:

Histogram(A,discrete)

 

It will calculate the frequency of each of the outcomes as they appear in the list and will plot them accordingly: 

How to prove that 

sum(binomial(n, r)*binomial(k+r, n), r = 0 .. n) = sum(binomial(n, r)*binomial(k, r)*2^r, r = 0 .. n)?

Maple calculates the LHS and RHS, but I cannot compare these with Maple for each n::posint and each k::posint s. t. k>= n. The question was asked in Mathematics SE. I don't understand whether it is answered there.

I am trying to see if Maple can help me find a closed form for an infinite series. I do this:

 

restart:

s:=Sum(n^2/((Pi^2*n^2+beta^2*epsilon^2)*(exp(n))^4), n = 1 .. infinity);

value(s);

 

Maple returns with:

Find a(n) of sequence 1 , 2 , 2 , 3 , 6 , 5 , 30 , 11 ,...
