Dear friends,

    The Physics package in Maple is a good tool for quantum physics. However, I came across some problems with the package when I performed a computation. Please see the figure.

The left-hand code (last two lines) shows Amx.Amy.Ket(x,1,1)=”-Ket(x,0,0)”. However, I believe that the answer is wrong; it seems that the negative sign should not be here.

The “am.Ket(B,4)=2ket(B,3)”

I'm going to put this plot into LaTeX, so it'd be nice if the font is similar. Both equations are functions of one variable.

Is there a nice, concise command to do this? Additionally, what's the easiest way to export this graph into a format useable by pdfLaTeX?

Thanks so much!

I'm running Maple 14, if that matters.

the integral
>int(1/x^2-cot(x)/x,x=0..infinity,CauchyPrincipalValue);
with Maple ?
Stars predict it equals Pi/2. Maple 13 easily cracks the integral
>int(tan(x)/x,x=0..infinity,CauchyPrincipalValue)=Pi/2.

Has anyone successfully integrated a 3D plot from Maple (X3D?) into PowerPoint that can be manipulated within a presentation?  I have read an article on Tecplot's (another graphics software package) web site that explains how to export a Tecplot file as an X3D file and then embedding the X3D file into PowerPoint using a X3D plug-in.  See below:

The X3D plot can...

This guy Giorges is using Python and wget inorder to do parrallel downloading
and he is arguing that it is very fast.

Now my questions become

1) Does there exist a simple way that I can use wget without installing it ?
I dont want to bother users of my Maple application with installing a 3:rd party software.
A simple file in a specific location would be ok though

UncertaityofCalibrat.mw

within the attached document, is the idea that I would like to develop with the optimization package.

What's wrong?
I need to minimize (z-Z) ^T.E^-1. (z-Z).
How can you see in the first Call to LSSolve worked. By introducing objectivejacobian I have problems

Recently, I submitted for publication to a peer-reviewed math journal

a formula for the n-th order implicit derivative given an implicit function G(z,w)=0.

i.e. dz/dw = - Gw/Gz where Gw and Gz are partial derivatives of G with respect to w and z, respectively. Anyway, I proved the general formula for d^n z/ dw^n.   I have since proved the generalization of this to implicit functions of several variables, G(z,w1,w2,...,w(N))=0. A good mathematician...

Dear All,

I would like to ask either MAPLE is capable to solve >2 boundaries value problem.

Actually I'm solving a system of ODEs in a membrane divided electrochemical cell, basically a REDOX process.In 1 part I have 2 species reacting and in another part I have 3 species reacting , 2 of the species exist in both part.

At the end I wanted to coupled all the species together.

So basically I have 4 boundaries and I would like to solve it simultaneosly.

Hi

My Maple 13 puts small curly brackets to the left side of an expression and this causes several problem for me. What should I change to write good ones? (I mean normal, big brackets, not small brackets to index.) (I use the AltGr+b combination to write a left curly bracket.)

Compare the results of isdifferentiable on 3 piecewise defined expressions f, g, and h.

The first time the order of the asking is f, g, h. The second time (after a restart) the order is h,g,f.

The results are remarkably different! What is going on?

isdifferentiable was first brought to my attention within the last week or so, maybe it is not reliable?

If you remove all the lines with 'assuming' then the inconsistency remains.

restart;

 Hi

I want to solve this Problem

Symbolic_Matrix.pdf

 in symbolic by maple, but i can`t.

is there any symbolic solution by maple or not,

if there is another solution please help me.

help_for_maple_quest.docplease give a explain how to work for operations.

Does anybody know how to make Maple 14 work with Visual Studio 10.0 Professional (not the express version)?  I can't seem to make this happen.  The problem has to do with the PostLink command.

Hi, again, I am a physist. It is convenient to solve problems in presence of units. I have a equation (1-variable) including a erf function to solve. As I substute all the constants (with units) and then use 'solve'. It returns a warning without any result. I am not really familiar with the numeric package in maple. Could anyone give me some advice? Thank you.
