Hi All,

I have a question that I see has been seldom discussed except certain posts by Mr. Lopez. This concerns the estimation of optimum parameters of the solution of a system of differential equations to fit experimental data. I referred to the Maple document provided by Mr. Lopez on the Maplesoft website.

Good morning.

I want to do a program in a worksheet that it can recall other workeet for plotting with display.

I don´t know how can recall other worksheets.

Please help me.

P.D.: I send a worksheet 01-06-2011-robot-man.mw

I have a pbs: Suppose 3 vector A, B,C with noted [A:B]:=(list)[ A,B,-A,-B] (i.e a paralelogram);

An endomorphism T such that T(.) where (.)=A,B or C are B,C, and (list)[C,-A,-B,-B]
 and T([x:y])=[T([x]):T([y])] where x,y = A,B or C.

Problem: draw T^{n}[A:B] , i.e its boundary is a fractal figure when n is big.

Hi everyone,

I am facing a very complicated system of nonlinear equation. This cannot be solve by using normal fsolve in Maple. Anyone can help me?

Thanks a lot

with(Physics):with(combinat):
comn := choose([u, v, mu, nu], 2):

def := seq(seq(seq(Physics[`.`](Dagger(Ket(aa, k)), Ket(bb, m)) = Physics[`.`](Ket(bb, m), Dagger(Ket(aa, k))), `in`(aa, comn[i][1])), `in`(bb, comn[i][2])), i = 1 .. nops(comn)), seq(seq(seq(Dagger(Physics[`.`](Dagger(Ket(aa, k)), Ket(bb, m)) = Physics[`.`](Ket(bb, m), Dagger(Ket(aa, k)))), `in`(aa, comn[i][1])), `in`(bb, comn[i][2])), i = 1 .. nops(comn));

I  used the DEtools package recently.

When working in a differential algebra with _Envdiffopdomain=[Dt,t] maple still returns something like Dt t^2. I would like him instead to assume, that Dt= dt/t and rewrite it as 2t + t^2 Dt. How can I achieve this behavior?

Hi , I'm Alan GHafur , I'm student in master dagree in Statistic in Irbil / Iraq .I want learn how can slove non linear function in Maple.

thank you for hlep me.

In 2D input it is possible to represnet

diff(f,x) as d/dx f

Is it possible to do

diff(f,x,x) as d^2/(dx)^2 f somehow?

Can one perform animation using the data file.

I want to animate the graph betweeen two variables say x and y, which I have stored in a data file. Does maple support any such operation?

Hi
I wrote a loop which is too long but I need its continuity so I wrote all of them in one loop.
The problem is too much time is needed to run it,even maple cannot run it.
I do not know whether my software has a problem or the way I wrote the program is wrong.
I attached the file.
thanks

Hello,

I have this problem. I would like to construct clothoid as a transition curve between two arcs. The length of this curve has to be 30 meters. The start azimuth is 0.3773 (rad) and the start radius is -355.835 m.

How could I do that simply in Maple?

Thank you

Like in the version 7 where that variable didn't exist.

There was a recent exchange I was a part of on Maple classic versus standard, etc. It disappeared from the list of "recent discussions" so I tried to track it by other means. A keyword search did not immediately return a helpful link, so I thought I would click on my profile and look for my recent comments from the lists there. But I could only find a list of "questions," "answers" and "posts". My contribution there was merely a "comment" and I can't seem to find any list about those...

would you please help me? 

I have a big problem in differentiating with maple! 

here is my equation. 

L := (alpha, beta, theta,alpha(t),beta(t),theta(t))

how can I find diff(L, alpha) ? 

L=(1/2)*I[a]*(diff(alpha(t), t))^2+(1/2)*I[b]*(diff(beta(t), t))^2+(1/2)*I[c]*(diff(theta(t), t))^2+(1/2)*m[3]*(b^2*(diff(beta(t), t))^2+(1/4)*C^2*(diff(theta(t), t))^2+b*c*(diff(beta(t), t...

Hi, friends

The physics package was provided a good tool to compute Commutator or anticommutator relations. Here, I met some problems.

Example 1:

      restart: with(Physics):Setup(mathematicanotaion=true):

      Setup (op={p[x],p[y]},p[z]):

      alg:=%commutator(p[z],p[x])=2p[x], %commutator(p[z],p[y])=-2p[y], %commutator(p[x],p[y])= p[z]
