Posted: Wed Apr 02, 2003 11:41 am    Post subject: oomath hangs with this formula

From http://www.oooforum.org/forum/posting.php?mode=quote&p=2559

It seems that oomath is bombing out on a certain formula I wrote.
This also happens when I'm embedding the formula in a text document.
Thanks to some help, I now know what the problem is, but I cannot see what is wrong here.
What I did is then retype the whole formula in oomath and save it. When I open it again oomath hangs.

Here is the formula:
 Code: func lim csub{x toward infinity}{{alignc 2 - func sin x} over {alignc x^3+3}} newline "For all " x " it holds that " newline matrix { alignr -1 #{}<={} #alignc func sin x #{}>={} # 1 ## alignr 1 # {} >= {} #alignc func -sin x #{}>={}# -1 ## alignr 3 # {} >= {} #alignc 2 - func sin x #{}<={}# 1 ## alignr {alignc 3}over{x^3+3} # {} >={} #{alignc 2 - func sin x}over{alignc x^3 + 3}#{}<={}#{alignc 1}over{x^3+3} }

Anyway, for what you wanted to to you could have worked with a table or tab settings, filling in each element with a separate formula object. The formula did not crash OOo anymore when I removed all the alignclausules you used. They are not needed anyway. Good luck!

There is a reference. Go the the help index under and you'll see a refernece... It has every command. It's all you need to use Math after you study mathematics for a while.

It's in the Wellcome to OpenOffice.org Math page (Help system), third link, called: "Reference"
