When I create any plot or drawing in Maple and print to pdf, the program adds a blank space underneath the plots. How can I stop this from happening?

Example: Some code I wrote, before hitting enter

After hitting enter
BTW if somebody knows how to avoid getting the extra [> I'm much obliged

And now a screenshot from the print to pdf

See the blank space which is suddenly added?! It really destroys my lay-out for my report. I think the solution must be an easy change in the settings, but I can't figure it out.

Thanks in advance

I'm trying to execute the program, which can be found here http://www.maplesoft.com/support/help/Maple/view.aspx?path=examples/pdsolve_boundaryconditions , but it does not work. I copied exactly what is written there:

restart; with(PDEtools):
U := diff_table(u(x,t)):
pde[1] := U[t]+c*U[x]=-lambda*U[];
bc[1] := eval(U[], t=0) = phi(x);
sys[1] := [pde[1], bc[1]];
pdsolve(sys[1]);

But after last command it just sais that

Error, (in pdsolve/sys/info) found functions with same name but depending on different arguments in the given DE system: [u(x,t), u(x,0)]

What's wrong?

Hello All,

I have 6 equations that are similair in size to the one listed below. I am trying to find a single equation in terms of only 1 of the variables (s₁₁). After finding this equation I want to solve it for that single variable. When I start plugging all these equations into eachother I get to about the last one then maple seems to get stuck evaluating. I left it on overnight thinking that if I gave it time it would eventually solve, but this didn't seem to work. My questions is, If I gave it enough time would it solve this? Is there another way to do this? Any help you guys could offer would be a great help. Thanks!

In another experiment with pdsolve, I am solving a PDE with two sets of boundary conditions. Unfortunately, after invoking pdsolve, I get no result at all. What can be wrong here?

Hi there! My name is Filippo, I'm a university student in Strategic Sciences in Turin, Italy.

I've recently started a course about Maple, how to use it, and now my task is to find examples in architectural buildings that are made using quadratic equations..I've found that the Beijin National Theatre is an Ellipsoid as well as the rugby ball...I've got troubles with model proportions,I mean which numbers should I put into my equation to get a nice Ellipsoid...this is what I've done (see pic).

Could you help me to find the right proportions for this model?

Thank you so much!

Can someone help me figure out what's going on? Here's the PDE I'm trying to solve, and I'm clearly getting the wrong answer.

If i have to solve the eq. i have to guess what U2 is  until i get close to U1 that the error is ok. can i do this in maple. or du i have to make program.

Does the installation of Maple toolbox for matlab removes MuPad in matlab? 

Now when I type in mupad in matlab, it says undefined function.

Is there a way to keep both?

Hello Everyone,

I would like  to write a code to calculate the riemann sum approximation of the curve sin(sqrt(x^2+y^2)+1 

calculate the actual volume using integration

use the ranges x=[-2pi to 2pi]=y, and 20 subdivisions.

also display the curve and the parallelepiped approximations on the same plot.

 my code give me  an error..please someone can advise me which part of my code is not correct..

Thanks very much in advance!

> g := proc (x, y) options operator, arrow; sin(sqrt(x^2+y^2))+1 end proc;

 Z := g(x, y);

 X := Array(0 .. n); Y := Array(0 .. n); Z := Array(0 .. n);

c := -2*Pi; d := 2*Pi;

a := -2*Pi; b := 2*Pi;

n := 15;

s := 0;

X[0] := a; Y[0] := c; Z := g[X[0], Y[0]]; s := 0;

dX := (b-a)/N;dY := (d-c)/N;

    for i from 0 to N do      for j from o to N do     s:=s+Z[i]*dX*dY     X[i]:=X[i-1]+dX: Y[i]:=Y[i-1]+dY: Z[i]:=g([Xi],[Yi])  end do;

This the error message i am getting (Error, unterminated loop)

Hi,

Recently a a simple problem which i can not handle by myself, made me confused.

I have simple code of maple which is not stable at all. Everytime I run the code, the final result which is the determinant of a matrix, changes and I can not see the problem with the code. In fact i noticed that problem occures when the matrix is being build by culculating the coefficients of some constant values.  I have attached the code. Could you see what is wrong here?

Thanks by the way.

code:

restart;
convert([92*x/790+18*x*(1-y)/1000=0.125,ln(46.59/x)=1/1.5*(ln(0.553/y)+2.5*ln((1-y)/(1-0.553)))],rational);
fsolve(%);
plots:-implicitplot(%%,x=0..2,y=0..1,numpoints=1000,thickness=2,gridlines,color=[blue,red]);

question:

there is something missing with the red line. I can't find the intersect point on the figure.

Is there something wrong with implicitplot? 

I purchased the student edition today, and after install and activation, it says the product is only available in 20 days. If I click the activate button, I repeat the successful activation process, but after another restart of Maple, the prompt comes out again, Eventually I clicked on OK, and I found that the license for me really expires in 20 days. 

I think it could be that my proof for student is not processed yet (no email), or a problem.

I wonder if there is anyone else purchased the student edition and encounter the same situation, and what is following next.

Hi everyone,

i'm trying to find out the euler angles from a rotation matrix.

I have a matrix that contains the result of multpilying the 3 axis rotation R(z,c)*R(y,b)*R(x,a) without knowing the values of the angles a,c,b (that's what I want to find out), so there are sinus and cosinus everywhere. There is another matrix containing the expected values that each equation in the first matrix will match.

My problem is that I eventually will change the order of the multiplication of the axis (i.e. R(x,a)*R(z,c)*R(y,b)) and I'm try to make maple compute this for me.

I defined R(x,a), R(y,b) and R(z,c) as follows:

Rx := Matrix (3,3, [1,0,0,0,cos(a),-sin(a),0,sin(a),cos(a)]);    
Ry := Matrix (3,3, [sin(b), 0, cos(b), 0, 1, 0, -sin(b), 0, cos(b)]);
Rz := Matrix (3,3, [cos(c), -sin(c), 0, sin(c), cos(c), 0, 0, 0, 1]);
and
RT := Multiply(Multiply(Rx,Rz),Ry);

Since here is alright. Now I want to match RT to the solution matrix.

g1 := RT[1,1] = mat[1,1];
g2 := RT[1,2] = mat[1,2];
g3 := RT[1,3] = mat[1,3];
g4 := RT[2,1] = mat[2,1];
g5 := RT[2,2] = mat[2,2];
g6 := RT[2,3] = mat[2,3];
g7 := RT[3,1] = mat[3,1];
g8 := RT[3,2] = mat[3,2];
g9 := RT[3,3] = mat[3,3];

soll := fsolve({g1,g2,g3,g4,g5,g6,g7,g8,g9},{a,b,c});

At this point I'm getting an error. I know that there are more equations than variables but the system is solvable anyway.
What maple trick can I do to solve this system or to find the good 3 equations?

Extra question:

Is there any method to match RT to mat without all those gX equations?

Thank you everyone.

Hi,

The default way a prompt shows on my maple is

[> blah blah blah

but i see in many worksheets including maple help pages that it shows as

> blah blah blah

My Question is how do i remove that left square bracket "[" from appearing ?

   Hi, there

 I work with maple 13 and made a file that its contet is plotting curves and its size is 

151 MB.Now when I want to open it the file cannot be opened completely only about a quarter of its contents rises.

Thanks for your help
