On p. 2 of the interview the following passage appears: "Since then, he feels that Maple has lost its battle with Mathematica."

That is interesting. I guess I have to read on to find out exactly why. Does he reveal that?

I completely agree concerning the font size: in the new smaller font the images in

http://www.mapleprimes.com/blog/john-fredsted/jacobians-and-hessians,

for instance, are almost unreadable.

I would have no objections to having equations displayed using MathML, that is after all what MathML was designed for. Thanks for mentioning it: even though I have a little experience with it I had not thought of it (I wonder why) in connection with mapleprimes.

But until then, if MathML is implemented, I would surely like to see my posts rendered visually correctly. I have to admit that having had to produce a visually ugly post as the one above is something I do not like at all: visual aesthetics is important to me.

I cannot help having the feeling that the issues raised in this thread, especially the one concerning the maple tag, are not taken seriously enough by MapleSoft. Jakubi's legitimate post has now lingered unanswered for three days. Why?

Of the three tags discussed in this thread, the malfunctioning of the maple tag is the most serious because users have no way to circumvent it. Although being a hassle, for the pre and code tags users can circumvent the less than optimal situation by switching back and forth between WYSIWYG view and source view.

To clearly illustrate the situation of the malfunctioning (at this time of writing) maple tag, below follows my desperate attempts to get a working image corresponding to the Maple input

Matrix(2,2,(i,j) -> i*j);
  • Writing <maple>Matrix([[1, 2], [2, 4]]);</maple> (the Maple output with an ending semicolon) in the source gives:

    Matrix([[1, 2], [2, 4]]);
  • Writing <maple>Matrix([[1, 2], [2, 4]])</maple> (the Maple output without an ending semicolon) in the source gives:

    Matrix([[1, 2], [2, 4]])
  • Writing <maple>Matrix(2,2,(i,j) -> i*j);</maple> (the Maple input itself, clearly I am just desperately fooling around by now) in the source gives:

    Matrix(2,2,(i,j) -> i*j);

Unless I am in serious need of a new pair of glasses, or have fundamentally misunderstood how the maple tag is intended to be used, I would say that these examples show quite clearly that the maple tag is (at this time of writing) malfunctioning.

Thanks for that tip, which returns the Classic Worksheet to the pool of potential future candidates.

I ask the same question: I can think of at least two posts of mine from this evening that I cannot find a link to anymore.

A little while ago the "Recent posts" looked all goofy, at one time showing only blog entries. Now it consists of posts of mixed type, but it is still incomplete. What is going on?

Thanks, Jacques, for these words of wisdom. Coming from a guy like you, having much more and much broader experience with different CAS's than I have, I guess I will do best in staying with Maple.

But then, of course, if I decide to upgrade (or use Maple 11, for that matter) I will have to change my ways of working, either using external editors, as earlier discussed here at mapleprimes, or follow some of the paths that you suggest.

Note added: Having just fired up Maple 11 Classic Worksheet and typed in some commands it seems that no auto completion is available. Is that correct? If affirmative, then I think that that route is a no-go to me.

Thanks, Acer, for that nicely compact version, which I will bookmark so that in the future I will be able to quickly locate it again.

I am not able to help your concerning the wobbles, but would it be acceptable to use plot instead, as shown below?

plot(1/18*(3*x+1)^2/x, x = 1/4 .. 1/2);
