The following example was shown to me by Matthias Kawski.

He noticed a difference in the way Maple 12 handles some definite integrals from the way they were done in Maple 8. Both cases point out some problems. I'll offer my explanation of the problem after I show what Matthias observed: First, the results from Maple 8. Each of these 4 examples evaluates a definite integral in two different ways, the first using a function and the second using an expression. All looks fine until the last example.

Hi there ! The attached worksheet has a good review on the theory of Limits and Continuity of functions that have two or more variables.

The attached worksheet has a specially designed tool that helps you evaluate the limits of really complicated multivariable functions.

Please feel free to ask questions.

For a single pair of left single quotes, ?name is clear:

Any valid Maple name formed without using left single quotes is precisely the same as the name formed by surrounding the name with left single quotes.

So this is fine:

`x`;
                      x

But what about multiple left single quotes? This help page also states:

If you have a standard math, complicated expression in your Maple worksheet that you would like to include in a blog in this venue, what's the most economical way to copy & paste it?

Maple gives different error messages to the same input depending on whether the input is done with Maple notation or 2D Math Input.

My example is to enter the following erroneous input in both Maple notation and 1D math notation:

plot( sin(x, x=0..1 );

Clearly this is missing a right parenthesis after the first x.

Here is how this section of my worksheet copies into MaplePrimes:

I find that for some plots the choice of location for tickmarks and axes labels in the Classic version is better than the Standard one. Eg. here:

with(plots):
complexplot3d(sin(z), z=-Pi-1.5*I..Pi+1.5*I,axes=boxed,
style=surfacecontour,tickmarks=[[-Pi=-Pi,0=0,Pi=Pi], 
default,default],orientation=[72,49]);

Okay, so September ended last week...but I am awake.

Seeing as we came to the end of another quarter (and this time I noticed it on time), we have to awards to distribute this month: 

How many arrangements of the word GELATINOUS are possible if the vowels must always be in alphabetical order?

Could MaplePrimes be made a little more robust?  It seems that roughly once a month I get a Drupal error all weekend instead of access to MaplePrimes.  I frequently have more time on the weekend to answer some questions, so it is the community that loses when the site is down... 

This has now happened frequently enough that clearly there is a systemic problem in the infrastructure, and it would be nice to know that it is being investigated and fixed.

When inserting standard math into a text region, Maple insists on converting even simple decimals like 0.01 into scientific notation.  Can I suppress that?

Which is the difference between them? (besides being builtin or not). For the simple examples that I have tested, their output seems the same, eg:

`convert/function`(f,[1]);
                                 f(1)

`?()`(f,[1]);
                                 f(1)

To be "updated" I have defined in Maple 12 an "identity function" using '_passed', but the output shows 'args':

id:=()->_passed; 
                           id := () -> args

Based on the paragraph:

Prior to Maple 10, _passed and _npassed were called args and nargs. For backward compatibility, these names will continue to work as synonyms for the new names.

from ?using_parameters, I find this result unexpected. In fact, I would have expected the other way round, ie that here:

Hi,

at the moment I am writing my bachelor thesis. I use maple to compute

the smith normal form of a matrix.

I would like to know whether there is some information about the complexity of maple's

implementation of the smithForm algorithm (package linearAlgebra).

Thanks,

Ever since upgrading to Ubuntu 8.04 I get Java debug messages when starting xmaple or when running maplets from the commandline maple. They look like this:

Hi there ! The attached worksheet has a good review on the theory of determining volumes of solids through the method called "volume by revolution". You can also view an interactive video that shows you how to use Maple's powerful Volume by Revolution tutor that will help you with your homework.
