Hi there,

I am currently working on an ODE model with a diffusion term and I have to analyse it analytically (if possible) with Maple12.

With the dsolve function I have a solution but based on BesselJ and BesselY functions.

My questions are:

• Do you know if it's possible to have a solution without these functions?
• When I add the IBCs conditions, the system is inconsistent, do you understand why?

If I search for something in mapleprimes then click on one of the selections, mapleprimes brings me to a page of many posts and does not bring me to the proper single post I expect to see.  In fact the post or question I selected does not even exist in the next page mapleprimes sends me to.

Hi I'm having trouble generating the mandlebrot set using maple... i only have a very basic knowledge of this programme.
>plot3d([-2, 0.7], [0.7, 3] orientation = [-90,0], grid = [250,250], style = patchnogrid, scaling = constrained, colour = mandelbrot);

The above code is giving me trouble, it keeps coming up with an error missing operator or ';'
I don't see anything wrong with it though....

Hi there,

I am trying to find the numerical value of the following integral:

evalf(int((T-a*n*(-T)^n+2*a*n^2*(-T)^n)/(T^2-a*T*(-T)^n+2*a*n^2*(-T)^n-2*a*n*(-T)^n), T = -90000 .. -29400)).

However, Maple just returns the integral. What am I doing wrong? 

Thanks!

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...

Hi,

I am using maple x64 to read/ open some large TIF files.   The files are 57 Mb each and I want to open 16 of them.  Maple looses kernal connection twards the end of the calculations each time.  This is anoying. Is there a way to fix this?

If I take the result form y and defign it as y and delete x them maple will calculate 1 more function set.

document setup;

x=read-image (using the actual maple commant)

y=entropy (x...

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!

I try to make a file using the fopen command, and maple keep telling me there is an operator missing:

fprintf(fd,'sous-total=%.2f$ \n total avec taxes=%.2f \n montant arrondi=%.2d$',sous_total,total,arrondi_total);

I used fopen before writing this, this line seems ok, I don't know why maple tell me this.

Can I have your help with this ?

Thanks.

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.
