I found in the help a reference that animation in uniparametric:

"plots[animate] - create a 2-D or 3-D animation on one parameter".

I need multiparametric animate. If it does not exist..it would be difficult to find somewhere the procedure written to get ANIMATE( for one parameter)?. If available, maybe it would be hard but possible to get something that performs a multiparametric animate.

Otherwise, if somebody knows that in MAPLE is impossible to implemente...

Hi

Can Maple work with differential operators without introducing a known function?

For example, assume that we have

diff(diff(f(x),x)+f(x),x);

How can we apply differential operators such as diff or D without applying any known function as:

diff(diff(...,x)+...,x);

if...

I have two issues.

if I say

int(exp(I*k*x),x=-Pi..Pi) assuming k::integer

Maple answers me with 

0

which is wrong, as one would expect the result to be a kronecker delta (k=0 is a type-integer for mapel). Is there a way to make Maple understand it is doing a mistake?

Related to this there is another point.

If I write

int(exp(I*(k-q)*x),x=-infinity..infinity)

Maple does not write (or convert) the result...

Hi

 I have a function as the following:

 temp:=phi(Lambda(tau, 0), tau, 0)+((D[1](phi))(Lambda(tau, 0), tau, 0)*(D[2](Lambda))(tau, 0)+(D[3](phi))(Lambda(tau, 0), tau, 0))*q;

 I have equivalent functions for Lambda(tau,0) and phi(Lambda(tau,0),tau,0) as the following:

 c[0](tau) instead of Lambda(tau,0)

y[0](c[0](tau),tau) instead of phi(Lambda(tau,0),tau,0)

Is there a simple way to allow for the input of a list of equations into a procedure?

I have these three equations:

f[1] := x[2]+3*x[4]+x[5]-x[6]=2;
f[2] := x[1]+2*x[2]-x[3]+x[4]+3*x[6]+x[7]=13;
f[3] := x[1]+x[2]-3*x[3]-x[4]+x[5]-x[8]=26;

Ideally I would want something like proc([f[1],f[2],f[3]]). Is something like this possible?

P.S. I have tried proc(f::algebraic) but got the error message:

Error, invalid input:...

I try to get the answer of int by newton cotes method,

but after runnig,it gives a complex number for the answer.

I think its because of singular point.

Is there any method which find singulaitis and make integarl to some parts without that singular point automatically?

thanks

i am wondering if anyone can give me some examples of functions that would help show the relationship between smooth functions and convergence of the fourier series so that i can graph these functions using maple over the period [-Pi,Pi]

I have 2 equations... f[1] := x[2]+x[3]+x[5]+x[6]=16; and f[2] := x[1]+x[2]-x[3]+x[4]+3*x[6]+x[7]=28; 

Is there a method that will allow me to count the number of equations?

Is there a method to display the indeterminants or variables which are in the equations i.e x[1],x[2],x[3],x[4],x[5],x[6],x[7]?

Is there a method to find the maximum indeterminant or variable from both the equations i.e x[7]?

Dear Maple helpers. Here a toy-version of my huge problems.

I want to do following:

1). Assuming (0 <a=1/2,  b=1/2, c=1/2)

I want  to plot (the surface of)  

f(x,y,z) = x^a * y^b * z^c   in the space (x,y,z) for

f(x,y,z)=50, 100 and 150, and with  x=0..40 ,  y=0..40, z=0..40

I tried with plot3d but it is not possible.  How could I do with Maple 14?...

I have a problem changing a maple matrix to a matlab code without getting the error

Error, (in PrintTarget) assigning to a long list, please use Arrays ( I don't know how to use arrays ) thanks Big in advance

Here is my code:

I tried solving the following equation but when i do i get

Is it not possible to solve for highly nonlinear equations ?

Hola;

one short question:

 How to apply random permutations of data within an matrix.

 --Shuffle-->

It was mentioned in the post that Maple can not solve some oscillatory integrals, mainly this one

int(cos(log(x)/x), x = 0 .. 1)

int(cos(log(x)/x), x = .001 .. 1) is okay

but we find that when we go from 0.0001 .. 1 Maple endlessly evaluates.  It seems as soon as we hit that 4th decimal there appears a problem. 

int(cos(log(x)/x), x = .00001 .. 0.0001) won't work either.  Oh, this is...

i want to use numerical technique to solve non linear ode.

are there some built in numerical techniques in maple13.?

kindly name few and there syntax.

i have seen that we can solve linear ode numerically. how can i check that what technique does maple use?
