Description Unknown 2002-11-24 17:06:21 UTC 
The editor is not able to display invervals that are only open on one side.

Concrete this means:

[a, b) and (a, b] can't be shown.
Comment 1 Unknown 2002-11-24 17:09:38 UTC 
And I just saw, that the editor is unable to handle this:

sup M
inf M
max M
min M

There should be a function that allows unimplemented functions to be
rendered correctly.
Comment 2 Unknown 2002-11-24 17:22:06 UTC 
and this...

the "in" symbol, that is the round E can't be shown at the begining of
the formula. I wanted to write "in setN" and then the editor shows a
mirrored question mark.
Comment 3 thomas.lange 2002-11-25 09:25:53 UTC 
Everything is working:

1) use sth like
      \[ a, b \) newline
      left ( a over b right ]

2) use
      func inf M func sup M
  this works even though sup also denotes the superscript 
  (see "a sup b")

3) since "in" is interpreted as binary operator it must have two
   arguments. Use
      {} in A newline
      {} in {}
   The {} can always be used where a argument would be required 
   and you won't like one.

The mirrored question mark shows that there was an error during the 
parsing of the formula, i.e. the syntax is not correct.


TL->MRU: Please close this one.

Yes, the described issue is a feature.
The formula editor was not designed to accept incomplete expreesions.
These are marked as "error" be the mirrored question mark.

Closed, because not a bug.
