### Invalid evaluation of derivative (more examples)...

November 09 2005
0 4
Additionally to my previous post: First example returns (mathematically) wrong result,
eval(diff(v(z), z), [v = (x->x*H), z = H])
2H

Equivalent works fine (just because multiplier "a" leads to implicit conversion of diff to D).
eval(diff(v(a*z), z), [v = (x->x*H), z = H, a = 1])
H

And the most exiting example (I think, that result can't be predicted by Maple developers also ):)))
eval(diff(v(x, y), x, y), {x = H, y = H})
(D[1,1](v))(H,H)+2 (D[1,2](v))(H,H)+(D[2,2](v))(H,H)

Functional analog works, of course, without any errors.

### Nice mathematical markup ideas?...

Hi, I think I will go crazy if I have to type
maple("printf(MathML:-ExportPresentation( ... ))");
one more time. It would be great to have an abbreviate version of this like
mapleml("...");
or something. Or how about a function available in the question bank editor to translate short LaTeX phrases into mathml? This would solve a huge number of my Maple T.A. issues. Anyway, along these lines, what I'd really like to do right now is ask my students about double integrals and display something like $\int\int_R f(x,y)\ dA$ Any suggestions? Can I use mathml() to display symbols like the integral?

The Maple User Group mailing list was once the main forum for asking questions and discussing Maple. Eventually the comp.soft-sys.math.maple newsgroup was proposed and the MUG list faded away. Some answers to specific questions are archived here, and all messages from 1998-2003 are available as digests.
