Any plans of correcting the obvious problem the MaplePrimes text editor has with the inequality sign < ?
It is really quite annoying.
Everything on a line of code after < is very often discarded with the obvious effect that the code doesn't run.

For a while I haven't received notifications about updates to answers and comments from MaplePrimes. Is that due to the recent problem with fake messages from Maple?

I know that I have raised this question before, and also got some responses.

However, I cannot find the thread, and I'm still interested in what is going on.

I don't have a clue.

end proc:

#Now try plotting what should be the parabola y = x^2 on the interval -1..1:

Compare the results of isdifferentiable on 3 piecewise defined expressions f, g, and h.

The first time the order of the asking is f, g, h. The second time (after a restart) the order is h,g,f.

The results are remarkably different! What is going on?

isdifferentiable was first brought to my attention within the last week or so, maybe it is not reliable?

If you remove all the lines with 'assuming' then the inconsistency remains.


If you make a misspelling in spacecurve as in

plots:-spacecurve([ARctan(t),t,t], t=0..10);

then Maple 13.02 (Standard) loses contact with the kernel.

Even if you forget 't ='  as in


Maple will lose contact.

It seems that also Maple 12 has a problem.

Maple 13 Classic doesn't have the problem.

Will these and other 3d-plot problems be corrected in Maple 14?
