I would like to investigate the JCHelpCallBack example using OpenMaple. The sample can be found under the directory,

$MAPLE/samples/OpenMaple/Java/jcmaple/

I've set LD_LIBRARY_PATH. And I can compile and run the jcmaple.java sample. That starts up what appears to be a commandline Maple session. And within that session I can issue the help query ?int OK. I can also issue INTERFACE_HELP(display,topic=int) and that too works, although it dispays as double-lined.

How do I convert a 2D expression constructed with MathMLEditor to a normal 1 D string? I know that example 6 from the maplet builder tutorial does this, but the result is often in a prefix notation. For example, if I enter "x-square + 1" as a 2D expression in the MathMLEditor, the result is `+`(x^2,1). I would like to get more normal x^2+1. I have examined the code generated by the maplet builder and experimented with options in the MathMLEditor and MathML[Import], but to no avail. Is there a way to convert the prefix notation to the more normal infix?

My login is rejected and I need a new password, again, and again.

I tried it under

Windows Xp- Firefox2.16, Firefox3, IE7, Opera9

Linux(Ubuntu)-Firefox2.14, Opera9

Since it is very uncomfortable I ask help, idea, suggestion.

Many thanks in advance and sorry a little bit off-topic.

To all,

I am trying to plot a procedure phi(beta, x) which uses dimensional units (length).  The code listed below returns an error message regarding "invalid units".  I have redefined the standard units to report length in inches, but I don't see why this should prevent me from plotting the procedure over a range of x (the procedure works when the arguments are specified discretely.  Thank you for your assistance.

Define constant beta:

I need mentorship and material that is going to assist me in how to use maple.

Hi all,

I have a particular system of partial differential equations to which I want to apply a change of variables involving square roots using PDEtools[dchange]. The result turns out to be not in a simple form due to the square roots. Why is this so ? Is there a better way solving the problem than the one I am suggesting below ? The system of partial differential equations of interest is the following:

Hallo Everybody,

I hope someone can help me.

I want to solve numerically the diffusion equation,

          diff(csh(rh, t), t) = Dif*(diff(rh^2*(diff(csh(rh, t), rh)), rh))/(r0*rh^2)

          where "Dif" is the diffusivity and "r0" is the initial value of rh (the equations were normalized).

subject to the following boundary and initial conditions:

I'm using Maple V R4 for OS/2 (the last version available for OS/2), and have two software questions:

- How do I change the font used in the math expression bar?
In the present font, which is fixed width, the parentheses
and bracket symbols, () and [], are almost indistinguish-
able. I'd like to use another fixed-width font that does
not have this problem.

- There seems to be a limit to the number of characters that
the expression bar will hold, limiting the size of the ex-
pression appearing in a text setting. Is there a way to
increase this limit?

Thanks.

I’m using maple 11. In my problem, I’ve five axioms: 

i am deriving lagrangian shape function symbolically for an 1-D element of order p in FEM....so the eleemnt will have p+1 nodes....

                 

                                   N(k,i) = product((X-Xother)) / product(Xcurrent-Xother)

Does anyone here know of any Maple code (public, or in the Maple Library, or on www.mapleapps.com, etc) that implements alpha-beta pruning?

I would like to see some examples of how this can be implemented and used in Maple, and possibly learn from it.

I recently asked about HTTP Requests and found out it could be done with either a Socket or with the HTTP package. The reason I asked is that I would like to connect to Blackboard (Course Management System). I would like Bb to launch a Maple worksheet or maplet and then Maple to be able to insert grades into the Bb gradebook. Does anyone know how to do that?

Hello fellow digitheads, I'm running the spanking new Maple 12 and I would like to graph the rather harmless expression for wave motion a sin(x - v*t) When I type it in and bring up the Plot Builder assistant it gives me the option (among many) of making one variable the animation variable and the other two "slidable". When I hit "Plot" an "Interactive Parameter Maplet" pops up where I can slide the value of those parameters while it cycles through the animation.

I´ve got problems with solving this task! Please help me with the solutions. Maybe someone knows how it works. I solved it from 1-4 and don´t know 5-8

Thanks

The Crank - rocker consists of rocker 1, coupler 2 and rocker 4. It´s connected with swivel joints. The rack is fixed.
We look at the  point mass m in A and the torsion spring (with damper) in B0. The weight and the inert force because of the motion affect in A (vx,vy ax,ay). All other components are without mass, rotary inertia could also been disregarded.
