MathML comes in two flavours: presentation and content, and Maple supports both. Find out more about this at ?MathML.

You will have to add the 'outputformat'='content' option to the MathMLEditor call, as the default is 'presentation'. The content is then automatically simplified to 2*x for your example. One could replace Import by ImportContent, but that's not necessary here.

My old wish related to that was that all NAG functions available were described in the help pages [...]

That feature is available in the Maple-NAG-Connector, a toolbox for accessing the complete NAG C library; see

http://www.maplesoft.com/products/toolboxes/nag/index.aspx

I guess it's by design, to prevent overly long outputs. You can alway request explicit expansion through

Im(expand(( u+i*v / u+i* v+lambda)^4));

If you want Maple to treat 'i' as the imaginary unit, you'll need interface(imaginaryunit='i').

I haven't gone through all details of this discussion, but isn't it a good reason to implement the incomplete beta function (numerically and symbolically)?

See e.g . http://en.wikipedia.org/wiki/Beta_function#Incomplete_beta_function for the definition.

Currently, we have the "complete" beta function available as Beta.

It's hard to give helpful hints without seeing your PDE system, but let's try:

If you have a solution such as your f(u,v) term, pdetest should be able to determine whether it solves the PDE (system). If the result is non-zero, you might be able to derive conditions on the constants c1, c2, etc. from it.

As for pdsolve, in the ?pdsolve help page, look up the paragraph beginning with

HINT = any algebraic expression

That way you can supply your own ansatz.

AFAIR; Maple V releases 3, 4 and 5 were all regarded as major versions (I'm not sure about 5.1), so there were no updates available per download. This is different from minor updates (patches), and for those old releases, the patches have been removed years ago, not recently.

If you want to purchase an update, you'll get the current version. Which won't run on a 486, of course.

The Computational Mathematics group at University of Kassel has experts on this topic. Please see www.mathematik.uni-kassel.de/~koepf/ for more information. Prof. Koepf has contributed many routines to Maple, e.g. the convert/FormalPowerSeries in Maple 11.

interface(prettyprint=0); will force Maple to generate 1-D output. The default in the GUIs is 3. Depending on your platform and terminal etc., you might need more interface settings such as interface(ansi=false) to prevent garbled output. Please enter ?interface to see the full list of options. If you need these settings permanently, just put them into your ~/.mapleinit file (if the compute server is running Unix). It will be read upon each (re)start.

The Maple Reporter is an electronic newsletter that keeps you current with the latest news. See here for subscription. RSS feeds can be found there as well (and also here on MaplePrimes). For books on Maple, please see the book list.

I'm not 100% sure about the issue here, but you should check your Maple version and build number (Help > About Maple). If it is Maple 11.01 Build 296069, then you should download and install a corrected version of the 11.01 update that is marked as Build 303882. See also the discussion in this thread.

The backspace key works as expected on our system (OS X 10.3.9 on a PPC Mac, hence slightly different from yours). Did you upgrade to 9.52 (available from here)?

You should contact Dr. Andrzej Pindor (University of Toronto), who introduced his QuantumAlgebra package at the Maple Summer Workshop 2004. I don't recall all the features, but Bra and Ket operators are available, including a nicely formatted output. His e-mail address is andrzej.pindor@utoronto.ca. I have not found any homepage or download address for the package. Maybe he is even active on MaplePrimes.

There are several approaches to do this in Maple. One that is particularly suited for finding all solutions in an interval is the Roots command in the Student[Calculus1] package. Here we go: Student:-Calculus1:-Roots(2*sin(2*x)-sqrt(3),x=0..2*Pi); As you see, I have inserted * characters where needed syntactically (in 2D math input, these can be omitted), and slightly changed your equation into an expression to put it into the Roots command. If you want to check graphically: plot(2*sin(2*x)-sqrt(3),x=0..2*Pi); P.S. Taking a course on trigonometry is not a mistake. ;-)

Here's an example to start and play with. Note that it's using the animate syntax that was introduced in Maple 9. plots[animate](plot,[sin(x+t),x=0..Pi],t=0..5); Once the first frame is plotted, click into the plot region and start the animation, either via the context bar (yellow triangle or slider) or the context menu (right-click to invoke it, then select Animate > Play). Please see ?plots,animate for more details about the command and its options. Further help about animation controls in the GUI is linked from there.

That's precisely what the coeff command is designed for: coefVAR1:=coeff(ROLL,VAR1); Please see ?coeff for more details. In particular, note that your expression ROLL will have to be a polynomial in VAR1. Generalized versions and other hints have been posted elsewhere on MaplePrimes; searching for "coeff" should help.
