Interested as well. 

Firstly how do we get from the noisy clown to the spectrum image?

The single quotes are delayed evaluation.  That would be where the confusion is coming from.

 

a := int(1/((1-(1/4)*t^2)*sqrt(-t^2+1)*sqrt(-4*t^2+1)), t);

                                          /     1      \
                    a := EllipticPi |  t,   - ,  2  | 
                                          \     4      /
evalf(subs(t = 3/2, a));

                  0.1560547979 - 1.261993176 I

For comparison M12 shows the plots as ...

Well that's interesting!  The plots in Maple 12 are shown as black.  However in mapleprimes they're shown in color and in Maple 2017 the last three plots are shown blank. 

For explicit purposes the commands should show

@Carl Love actually the arrows aren't white otherwise you would see the boxed axes dissappearing as a white arrow passed in front. 

In fact arrows=THICK is the only option that makes shading=none work.  SLIM, LINE, and THIN don't produce any visible change from the empty plot.

Oh, ok.  But with no shading they should be black arrows.  I don't know why it changed to white, there should have been no reason for the programming change.

fieldplot3d([2*x, 2*y, 1], x = -1 .. 1, y = -1 .. 1, z = -1 .. 1, grid = [5, 5, 5], shading = none)

It works in Maple 12 and I think Maple 13 but at least from maple 18 on, shading=none does not work. 

 

@mapleatha with Maple 13 the standard GUI comes with classic.  This will load the standard GUI, (I'm guessing you're using windows)

 

You've probably been using a shortcut which loads classic, which is the same as doing this

 

So I believe what you mean is ..

@hpc insequence=true merely means to execute the sequence of plots consecutively.

@tomleslie thanks.  I appreciate your work on the subject.  Another tough word is "doable". 

Your example of dealmaker and deactivate are examples of two different types of words, one is a combination of two words "deal-maker" while the other is a word with a prefix "de-activate".

I think if we create enough rules we can crack the syllable code, but perhaps there are too many one off rules that make the code impossible to complete?

Any thoughts as to why StringTools(SyllableLength) has not been fixed in Maple yet?

ok thanks.  The table wouldn't necessarily contain expressions but a combination thereof with descriptions.  I have implemented an idea but it's not very maliable which makes it difficult to change or manipulate in the future.  I was also trying to programmatically fill the table which would reduce the enormity of the task .. thinking about it just now I could probably manage without. 

Thanks for the info though.
