## Problem : How to assign variables to a list of exp...

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

Hi everybody,
i'm an italian student, i'd like to create a Maple Library Archive for Maple 11 (a .mla file) with the procedures i want but i don't know how to. Can anyone explain me?

(I want to create a .mla file with some procedures and then recall the library at the initialization of a new worksheet, so that i can use the procedures i defined)

For example, i would like to create a .mla archive with the 2 following procedures:

## How do I export to latex?...

Hi,

I'm using Maple 11 and pdflatex. I'm trying to export Maple code to latex.  To this end, I've exported my maple file as a latex file and included the maplestd2e package in my tex document. However, from compiling the tex file I only obtain pdf output for those parts of the original maple file that represent output. For example, the following tex-code correctly produces the word 'true':

\mapleresult
\begin{maplelatex}
\mapleinline{inert}{2d}{true}{$\displaystyle {\it true}$}

## plot nimations with more than one parameter...

Hi there,

I want to know how I can animate a plot with more than one parameter? I can manage animating a plot with one parameter, using the 'animate' command, but this seems to be limited to a single parameter.

How could I do it? If it is not possivle in Maple 11, would such an option be implemented in Maple 15?

Also: If I would want to animate other things than plots, are there commands for that in Maple 11 / 15?

Thx :)

## How to get the range of a function given it's doma...

Hi there,

I was woundering if there is a function implemented in Maple11, where I can enter a function and it's domain, and the output is the range. For example:

Entering f(x)=x^2, and the Domain x in (-1,2), I would want Maple to tell me that f(x) is in [0,4).

Is there such a function implemented? I need this quite often, most times on functions from R->R, but also more general for functions from R^n -> R^m. I know that in some cases you could...

## Assign linestyle in LineChart plot...

Hello,

I have the following problem:

I have an array of values stored in F[i,j] and plot them using the LineChart tool:

LineChart([seq([seq(F[i, j], j = dmin .. dmax)], i = 1 .. 3)], xcoords = [seq(0.1e-1*2^(k-1), k = dmin .. dmax)],  color = mycolor);

This way, I obtain 3 curves, each of them with a different color as defined by mycolor.

However, for a publication in black and white I would now like to assign different linestyles...

## Version Compatibility Maple 11 & Maple 12 - Ritz M...

Hello,

I am trying to use a worksheet developed by Professor Batista [ritz06.mws] for calculating plate vibration frequencies using the Ritz method, which is available from the Applications directory - Mechanical Engineering folder.  The worksheet was developed using Maple 12 and I am using Maple 11; a careful reading of the file didn't show any commands that were incompatible across the two versions and yet I am not able to solve the worksheet using the default inputs provided in the worksheet.  I have attached a PDF output of the file with the error message.  Any assistance that could be offered would be greatly appreciated.

Kind regards,
