You can also avoid creating the a~ altogether:

simplify(f(a)) assuming 0<a<Pi/2

Do you mean K(y,z)[x] or K[y,z][x] ? If the latter (i.e. you have multivariate polynomials in x,y and z) and your finite field is a prime field, have a look at ?PRem.

If you really are looking at rational functions in y and z as your coefficient field or K is a more general field, you'll want to use ?Domains.

I hope this helps

There seems to be something wrong with the code to produce the plots. I am getting 'undefined' in some of the variables.

My advice would be to get the code out of the embedded components and into a procedure (perhaps called Update) in the worksheet. Calling that procedure will then read the current values from the embedded components and update the plot. It will be much easier to debug the code in that way. Once the code is working, you can simply add a call to Update() to all the sliders and buttons. For cleanup, you could then move the code into the startup code region (which you get by clicking the gear icon in the toolbar).

I hope this helps

It would help if you could post the model that you are having problems with.

In general, MapleSim 4.5 deals much better with systems that have a lot of events than versions 4 and earlier.

Any version control system should work with .msim files. Internally at Maplesoft, we use perforce.

A tighter integration with version control systems that would allow seeing diffs from one version to the next is on our roadmap but I can't give you a timeframe for when you're going to see this in a released product.

Try this:

> kernelopts(opaquemodules=false);
> print(Student[NumericalAnalysis][Newton]:-ModuleApply);
> print(Student[NumericalAnalysis][Roots]:-ModuleApply);

In Maple 15, the DataTable might work better for this purpose. It's linked directly to an underlying matrix and changes to that matrix immediately reflect on the table (as well as the other way around)

Yes, there will be lots of goodies in Maple 15. More soon.... :-)

I realize that a big announcement like this can cause some uncertainty and would like to clarify a few points.

Yes, Maplesoft has seen growth from the engineering market over the past years. However, mathematicians continue to form the majority of our customers and we spend a lot of mindshare on how to continue to provide new features for this audience with every release.

We also continue to work together with math researchers around the world and Maple continues to lead the pack in areas like differential equations and polynomial system solving, as a result.

I don’t expect any of this to change with the acquisition. Cybernet, btw, has been our reseller in Japan for many years and counts a large number of academic Maple users among its customers.

Please don’t hesitate to contact me if you have any further concerns about our direction

The Standard worksheet interface helps prevent such problems by refusing to display expressions that are too large or by only partially displaying such expressions. The defaul behaviour can be changed in the options dialog (look for "elision" in the "Precision" tab.
