There is a cool option of dropping one graph from multigraph (after that it goes as separated one). How to get  this dropped structure itself? I.e. i have "graph" component with command AllPlots that itself is

AllPlots:=plots[display](AllPlotsStructure,...);

AllPlotsStructure is a list of plot/textplot.

After all i removed one structure by drag-and-drop on component. How to update AllPlotsStructure correctly?

Hi!

I have a sequence of difference polynomials (which I obtained by the method of finite differences) and I would like to find out if there is a recurrence relation between them.

The generating function of general difference polynomials is given by:

HI,

I want to create a Textbox which will be opened in the beginning of a Maple code. In this Textbox I want to write an integer, which will be used for a following calculation.

I already found this code:

> restart; with(Maplets[Elements]);
print(`output redirected...`); # input placeholder
> maplet := Maplet([["Insert Text", BoxCell(TextBox['IB1'](1 .. 10))], [Button("OK", Shutdown(['IB1'])), Button("Cancel", Shutdown())]]);

Problem: Let (d): x = 2*t + 3, y = t -2, z = -t -1 be a line and (P): x+ y + z + 2 = 0 be a plane. Write the equation of a line Delta lies in the plane (P), Delta perpendicular to the line (d

I tried to solve a non linear coupled boundary value problem in MAPLE using DSolve command. The code is :

alias(eta = e, theta = t)

Eq[1] := 5*(diff(F(e), `$`(e, 3)))+(m+3)*F(e)*(diff(F(e), `$`(e, 2)))-(2*m+1)*(diff(F(e), e))^2-(4*m+2)*H(e)-(m-2)*e*(diff(H(e), e)) = 0

Eq[2] := diff(H(e), e) = t(e)

Eq[3] := 5*(diff(t(e), `$`(e, 2)))/Pr-(m+3)*F(e)*(diff(t(e), e))-5*m*(diff(F(e), e))*t(e) = 0

BCs := [F(0), (D(F))(0), (D(F))(infinity), t(0)-1, t(infinity), H(infinity)]

Hi

I have a program which I need to exit a loop when an error is thrown. it should then output the value of a. but it doesn't....

Hi everyone,

In MapleSim, I know that after running a model simulation, one can save the data via 'export data in excel or csv' format...

But is it possible to automate this process via a script? For example, if I wanted to see what the model data looks like by varying one parametere between 10 to 50?

Example:

for i = 1:50

   variable_in_model = i;

   run MapleSim model;

   save MapleSim model data;

Hello, I've got a simple question in Maple7. I tried to fill the array "intXdA()" in the for-loop but I failed. How I have to declare it after "global" in the beginning? Is it possible to declare it after "n" is determined - so that it has n elements?

restart:
with(plots):


> flsp:= proc(f,ug,og) global i,n,intXdA()
   y:=unapply(f,x):
   if  ug<0 and og=0 then n:=1 end if:
   if ug<0 and og>0 then n:=2 end if:

Hi,

I would like to discribe the following function.

w(ξ,s):=N(s)*w(ξ)

N(s) and w(ξ) are both matrix. I have defined N(s) but will be searching for w(ξ) much later in the process. Why does it not allow me to define a partial derivative of w(ξ) now for future use? d/dξ(w(ξ)) is not allowed. it says that "Error, invalid input: w uses a 2nd argument, s, which is missing". But my w(ξ) only depends on the variable ξ.

2nd question, how do i tell maple that x...

Hello,

I am trying to run maple file for k=1, k=2 ....

My do-loop did not work. What I would like to do is to solve the ODE then have new inc and solve it again.

I should have U(405) then U(770) ....

> restart;

> with(DEtools); with(plots);

> lambda := 0.1; delta := .5;

tau := 40;

> for k to 3 do 365*k end do;

> ode := diff(U(t), t) = -lambda(t)*U(t)*U(t);

> inc1 := U(0) = 100;

Need to do in maple smth like that:

I am searching for an analytical solution, if one exists, of a first-order differential equation of the Chini type, which is a generalization of the Abel type. The equation I'm trying to solve is very closely related to one presented in Maple's help files and which does admit an integral representation, namely the equation reported by Kamke as number 152 (according to the reference given in Maple). The equation I'm grappling with is similar to Kamke152 but with the forcing...

Let A(2;-2;3), B(4;-5;6) and (M(1;2;3) be three points. Write the equation of the plane (P) passing through two points A and B 

Problem: Write the equation internal bisector and external bisector of a triangle ABC with A(1,2,-7), B(3,-1,-1), C(-5,14,-3). This is my code.

in the commands M = A + v*t and M = A + u*t, please comment for me. Thank you.

Hello everybody,

I represented a polynomial P type:
P := a + b*x + c*x^2-d*y + e*y^2 + f*x*y
(where a, b, c, d, e, d, are real)

using fucntion pointplot3D
G1 := plot3d(P, x = 0 .. 5, y = -0,5 .. 1);
display(G1);

I represented this polynomial which look like a paraboloid.

I'm just wondering if I can animate continuously...
