Hey guys. I seem to have hit a few nasty snags while trying to create Maplets, I wanted to ask a few questions to the guru's here to make sure I can do what I want to instead of wasting time trying to find it. First off: Can I create a GUI in which I can have tabs so that I can have multiple pages worth of actions in seperate segments. For example, I want to illustrate how to do 6 different types of questions. however I don't want EVERYTHING on one screen. Is this possible? Also, I want to create a grid like system for a circuit, given some initial input. Can I pass parameters so that when the circuit tab is pressed a frame is popped up (or another maplet), that takes in input, and passes it on to the main Maplet program?

Hello, I would like to convert Maple solutions to Matlab code. Is there a simple package or Maple code doing that ? I do not want to create a permanent link between Maple and Matlab with a toolbox but simply convert the Maple code to a Matlab code. Thanks a lot ! Guillaume

I would like some help on how to include mathml formulas from Maple in jsp pages for Maplenet. I use de MathML:-ExportPresentation to obtain the mathml form from Maple, but I cannot see it correctly in a jsp page. It seems mathml works fine when I have a html page. I would like to know if is there anything else I should do so that i can work in jsp too. Thanks

I have learned in Brownstone site how to create,
using latex, sketch questions for Maple TA.
I could create a question bank, formed by sketch mode questions,
and then uploaded it to Maple TA, but the applets just don't work.
There are no java error messages.
On the java console i get messages like:
--------------------------------------------
false
false

SplinePlot.mousePressed():
Could not add node because of conflicting x-coordinate:
node with matching x-value already present in system
Please select another point.

I cannot install MapleTA 2.51 with SUSE 10.1. It gives the same errors as I see in the forum for Maple 10. The suggested fix for installing Maple 10, commenting out the "export LD..." line, only leads to a new install error. It says that a ".Z" file is not a gzip file. Has anyone installed MapleTA 2.51 on SUSE 10.1 successfully?

I wasn't sure of the details of non-Maple-owners accessing Maple content via MaplePrimes. Do they have to be members of MaplePrimes (can non-Maple-owners be members of MaplePrimes?) Either way, where can they go to access the content? I understand how to upload and access my own content via the file manager, but I don't understand how it can be made available to and viewed by others. Thanks a lot.

Hi. I'd like to write a maple TA question involving a sketch. There are standard tests used to evaluate whether the sketch designed by the student is correct, such as : \check{linear} \check{goes_through(0,1)} etc... There is a certain tolerance in these tests. If the sketch aproximately goes through point (0,1) in the previous example, it will be considered correct. My questions are : What is this tolerance ? Is it possible to set this tolerance ? if not, Is it possible to artificially create a tolerance factor (with something which would look like : (value(0)-1)

Hi, is there a way to install the maple toolbox for labview under LV 8? During installation process i receive an error message that LV 7.1 is necessary. Thanks for any help, Tom

In order to generate a 2x2-matrix in the question text I use
$display_matrix =maple("printf(MathML:-ExportPresentation(<<($a),($c)>|<($c),($b)>>))");
where $a, $b, $c are random numbers (see below for full question source).

In MapleTA 2.0.1 the question operates correctly. I quote here an exemplatory call to Maple taken from the console:

jvm 1 | To Maple --> printf(MathML:-ExportPresentation(<<(-4),(6^(1/2))>|<(
6^(1/2)),(-5)>>))

However, instead of depicting the corresponding matrix, MapleTA 2.5 depicts the Maple code. That this will happen can also clearly be seen in the call to Maple:

jvm 1 | To Maple --> printf("%m", 'Matrix(2,2,{(1, 1) = -2, (1, 2) = 2*2^(1
/2), (2, 1) = 2*2^(1/2), (2, 2) = -4},datatype = anything,storage = rectangular,
order = Fortran_order,shape = [])');

How does it come that MapleTA 2.5 decides to add "%m" to printf? Is there a possibility to fix this by making appropriate changes in a setup file?

I would be grateful for any hint.

Peter

Hello,

I am trying to plot a function via

\drawMaplePlot*{plot($m*(t-$t0),t=0..$tmax,labels=["t in a.u." ,"a in a.u."], labeldirections=[HORIZONTAL,VERTICAL])}

using LaTeX-authoring. This will result in

drawMaplePlot("plot($m*(t-$t0),t=0..$tmax,labels=["t in a.u." ,"a in a.u."], labeldirections=[HORIZONTAL,VERTICAL])",250,250);

in the edu-file. The problem is that the second " is interpreted as the end of the argument to drawMaplePlot.
What is the escape character for "? Escaping by \, i.e. \" does not work.

Of course the maple command
plot(m*(t-t0),t=0..tmax,labels=["t in a.u." ,"a in a.u."], labeldirections=[HORIZONTAL,VERTICAL])

I have encountered two problems with the symbolic editor in Maple T.A. 2.5. Both problems do not occur in Version 2.0.1:

Problem 1: Typesetting x^$n in authoring a question.
This will result in

Hello, currently I am trying to find out about the java(CN,a,b,c,d,...) function named in the Maple TA help. I just knocked together a small class which implements the named public function public String eval(String[ ] args); I tried to figure out the right place for my class. So I created a *.jar file containing it. I put it inside the "java" directory contained in the Maple TA install dir. But this does not work. :-( Right now I am wondering where to put this class and/or jar-file?! Has anybody used this function and is able to help me out? I would be really thankful for a hint because that function promises to be very useful...

I was trying to generate a derivative of randomized order in Maple T.A.
It seems impossible to me since the $ in the Maple syntax of
diff(function,x$n)
and the $ in the Maple T.A./brownstone syntax needed to denote a variable are incompatible.

Coding, for instance,
$n = range(2,5,1);
$function = maple("diff(x^5,x$($n))");
or
$n = range(2,5,1);
$function = maple("diff(x^5,x$$n)");
in the algorithm section makes Maple T.A. complain about a syntax error immediately

Coding
$n = range(2,5,1);
$function = maple("diff(x^5,x$n)");
leads to
jvm 1 | To Maple --> diff(x^5,x2)
being passed to Maple (taken from wrapper output).

Hi, I think I will go crazy if I have to type

maple("printf(MathML:-ExportPresentation( ... ))");

one more time. It would be great to have an abbreviate version of this like

mapleml("...");

or something. Or how about a function available in the question bank editor to translate short LaTeX phrases into mathml? This would solve a huge number of my Maple T.A. issues. Anyway, along these lines, what I'd really like to do right now is ask my students about double integrals and display something like $\int\int_R f(x,y)\ dA$ Any suggestions? Can I use mathml() to display symbols like the integral?
