## how do i solve the problems in physcis packge...

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)”

## How do I make a monochrome plot for two equations,...

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.

## How to calculate...

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.

## NLPSolve in Matrix Form - variable problem dimensi...

Hello,

I ran into problems while trying to write the input to NLPSolve in the Matrix Form because the problem dimensions depend on the input data. Take the following example:

max f(x)           <- f a nonlinear function of x

st: x1+x2+x3+x4                     ≤ b

## Interactive use of Maple 3D plots within Power Poi...

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...

## Error message - can't edit!...

Hi,

This error has occured for me several times, and I can't seem to find any way around it.

When I make an error in either the algorithm or especially in the grading part, I sometimes get something like this:

Part 2: The character ; cannot be used in a formula.

...or some other error message. I can figure out what I've done wrong and how I might fix it, but I cannot edit the question. Whenever I click on "edit", all I get is the error message....

## Convert combinat:-permute in Maple to Matlab...

Hello,

I would like to convert this Maple code into Matlab. Matlab() gives me "Warning, the function names {`\$`} are not recognized in the target language"

Here is the code:
for d1 from 2 to r-1 do

for l to d1 do Z[d1][l] := combinat:-permute([`\$`(0, d1-l), `\$`(1, l)]);

K[d1][l] := factorial(d1)/(factorial(l)*factorial(d1-l))

end do

end do; Z[2][1][1][1]; K[2][1]

Thanks and cheers :)

## python script, wget and Maple...

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

## minimization problem...

UncertaityofCalibrat.mw

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

## minimize (z-Z) ^%T.E^-1. (z-Z)....

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

## Literature search for an implicit differentiation ...

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...

## When will the size of the arrows for expand docks ...

includes Greek, Components etc. Then I selected components
and droped it on the righ-hand side of the screen, which gave me
a dock on the right-hand-side of the screen.

Now the problem is when you want to remove such a right-hand side dock.
The arrows are extremely small which means that it is extremly difficult to
see them yet alone click on them. Most of the time when you have your mouse on them

## Is there any solve?...

If you see my last question "use fsolve or matrix dissection"CCC.mw

I want to find C, i finally solve it and get My special C

Now , I Want tolve My problem in block mode,
CCCd.mw

this means that, My matrix elemnts are block matrix, and search for result,

## Boundary conditions...

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.
