Hello:

I'm studying many time ago the quantum chemistry of rectivity . so far, I can arrive to news theories from my experince on Maple productcs as they are incorporated in my theoric equations. I have glad  on communicat my previous results on Chemical Reactivity and Uniffied Field. botn of those ara closely related and my purpose is obtain diffusion and comments on these.

- My first paper was on Chemical Reactivity (Kinetics and Dynamics) and...

How can we draw a sequence of segments with a list data of column vector? Thanks

In Arfken(Mathematical methods for physicists,5-th edition,page 483),the asymptotic form of the Hankel function is approximated as

H1(t,s)=

Is there any simple/direct way in Maple(using HankelH1(),or otherwise) to achieve this?I don't want to assign numerical values to t or s.

I'm using Maple 15.  It seems to me this worked in some previous version...

Consider the Lambert W function, y=LambertW(0,x) ... I want Maple to tell me the asymptotics for it,

something like this:

But I don't get that now.  Is my memory faulty that I got it in the past?

Maple 15:

  asympt(LambertW(0,x),x);

not very useful...

series(LambertW(0,x),x=infinity);

with(MultiSeries):
series(LambertW(0,x),x=infinity);

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

Dear all,

The results I get from calcultion are usually not in compact forms, so I want to do some simplifying work. And I come up with some questions.

If I write the following expression, the factor command works:
> beta[c]^3/exp(I*omega[c]*tau)-beta[c]^2/(exp(I*omega[c]*tau))^2-2*beta[c]^2+2*beta[c]/exp(I*omega[c]*tau)+beta[c]*exp(I*omega[c]*tau)-1;
> factor(%);
   
However,when I write the above expressoin as following,  factor doesn't work

Hello everybody,

I would like to assign 349 different variable not already existing (w[i], i from 1 to 349) to 349 expressions from a list. Unfortunately I do not know how to write it. When I try anything like a:=w[33]->listevnouveau[33], it does not work.

With this a, I want to solve this : solve(listedd[33]*w[33]=a,w[33]); which is only possible by assigning variable to the expression.

Regard, Charbo

Is there a direct command to give the (first) index in a list,
for which the entry coincides with some given value (without
coding a loop, to run through the list)?

PS: when I enter that question I automatically get an info,
that similar questions exists. But clicking on those links do
not give usefull infos, they just lead to a page of old threads
(Page 529 of 569 for the first link ...)

Hi all

I am trying to draw a 3d plot from the data that I have created in excel, how do I import from excel to maple and then draw the 3d plot using array?

below is the link to my dataset in excel

your help is appreciated

How I can say that an object,say k, is a constant(it may be positive or negative) inside assume()?

assume(k::??should I say)

pls also tell me what kind of help pages I should see for this kind of "type inside assume()" problems. 

Thanks.

I was recently browsing the Wolfram website, in particular the Online Integrator, and was very impressed that they are exposing a part of their product for free public use. I also noticed that they offer the option of submitting previously unknown anti-derivatives to them:

I have three different matrices, say A(3x6),B(3x6) and C(3x12) with the size of each matrix mentioned within parenthesis. I want to define a fourth matrix D (6x12) so that D=[A,B;C] (in Matlab notation). Can anyone please tell me how to define this D in Maple? Maple help seems not that helpful at least for beginners like me. Thank you in advance.
