Hello

Is there a way to change FPS via options in an animated curve?

Hello,

I have several figures generated by ZeroPolePlot command, I feel the figures are not the size which I expect, so I can make the figures a little bigger or smaller by dragging the edge of them. But for several figures, it is difficult to make them to be just the same size, namely, all the figures' height=200, weidth=200. In one thread, Mr. Robert...

The orginial equation to solve is : x" + F(x) = sin 4t

initial conditions : x(0) = 0, x'(0) =1;

F(x) = { bx, x>= 0 and ax, x<0}

I need to do three different values for b = 1, a = 4, then b = 64, a = 4, finially  b = 36, a = 25,

Thanks for any insite I am new to the program.

I have a simple request that I hope someone can provide, I do not think it would be too much trouble.

I use Maple 12, hence no Maple cloud, but while viewing one of the maple 14 demonstration videos there was a Maplesoft document in the cloud called -  Example: Mortgage calculator by maplesoft, I would like to have a look at it.  Upon using google and the maplesoft application center, I was unable to find such a document. I am guessing it only exists in the maple cloud.

SORRY IGNORE THE LAST GRAPH AND PLOT IT NOTHING TO DO WITH THIS QUESTION!!

I'm having a few problems with differentiating in Maple. I have a potential function U given by:

U[c] := (1/2)*r^2+M[1]/r[1]+M[2]/r[2];

U[r] := r^2*(M[1]*M[2]-3)/(2*c^2)+((x(tau)+diff(y(tau), tau))^2+(y(tau)-(diff(x(tau), tau)))^2)^2/(8*c^2)+3*(M[1]/r[1]+M[2]/r[2])*((x(tau)+diff(y(tau), tau))^2+(y(tau)-(diff(x(tau), tau)))^2)/(2*c^2)-(M[1]/r[1]+M[2]/r[2])^2/(2*c^2)-M[1]*M[2]*(1/r[1]+(1/r[1]-1/r[2])*(1-3*mu-7*x(tau)-8*(diff(y(tau), tau)))+y(tau)^2*(M[2]/r[1]^3+M[1]/r[2]^3))/(2*c^2);

Hi All,

Is using the NAG package the right way to go about creating the delaunay triangulation of a set of points in 3 dimensions. My points all lie on a surface in R^3.

Thanks. 

Hi All,

Recently I upgraded to Maple 14 from Maple 13, and I've encountered a strange behavior in Maple 14 that doesn't appear in Maple 13. By the definition of Spherical harmonic functions in Maple,  

SphericalY(2*l, -2*l, theta, phi) = SphericalY(2*l, 2*l, theta, phi).

And this is true in Maple 13, however not Maple 14. Can you reproduce this behavior in Maple 14? Or have I done something else that might be causing this?

Thank you for any help you can provide.

Hi there,

I have defined an own type MyType wich is internally just a list ['MyType', A, B] with let's say two lists A,B and the symbol 'MyType' as first element (to identify the type).

Now, if I define

X := MyType('MyType', A, B);

is there a possibility to extract A out of X by something like

X[2]

or even better X[1] (thus skipping the first one)? The only thing I know is op(2, X).

Hello,

I need to create a new bernoulli distribution such that P(I=1) = q = 1-P(I=-1).

I did U:=Distribution(PDF=(t->piecewise(t=-1,1-q,t=1,q,0))); but Maple gives me back:

module() option Distribution, Continuous; export...   instead of:

module() option Distribution, Discrete; export...  since the distribution is discrete!!

Do you know a way to force U to be a discrete distribution, cause otherwise I get all moments=0.

hi all

is there any (possibly simple) way to distribute a piece of maple software not allowing external user to access the source code ?

Translating to C, compiling and then including as an external function is very awkward procedure.

thanks in advance

Hello!

I'm trying to solve numerically an ODE system with piecewise. And this piecewise is very important for this task.

This system describes behavior of a pulley with friction. There are some constants: m, c, g, mu and J. Values of this constants are not important.

> sys := m*a(t) = piecewise(a(t) < a0, F0*time, a(t) >= a0, 0), v(t) = diff(x(t), t), a(t) = diff(v(t), t);
> m := 5; F0 := 10; a0 := 5;
> initialconditions := x(0) = 0, v(0) = 0;

Dear folks,

 In mapple programming while assigning a fraction to a variable...it directly simplifies it....

eg: x:=4/6 and it directly gives 2/3

can we make mapple not to simlify this fraction....

It is very important for me to find out....

please help me

thanks in advance

regards

uday

I have looked at the maple help for the ErrorPlot function, but i can't make it work for my plot. 

I have the following procedure:

K := 1.; Xrng := [seq(dt*i, i = 0 .. ntime)];

value := array(1 .. ntime+1);

ave := array(1 .. ntime+1);

for j to ntime+1 do:

discountfactor := exp(-r*j*dt);

Stot := 0.;

Stot1 := 0.;

for i to npath do:

Spath := max(Spot[i][j]-K, 0);

Stot := Stot+Spath;
