HowTo or FAQ for "how to write aligned equations"
Last modified: 2008-11-11 08:27:13 UTC
A repeating problem occurs with how to write series of equations aligned along to "=" sign (or other symbols) as usual in a professionally printed literature (see issues 5998, 29053). There is a good workaround for it, but you have to know the things *really* well first to reach the goal. That's why I would recommend to add a "cookbook tip" in on-line help (that's where I - an average Joe - go when I have a problem; I had no idea there was some FAQ and it is quite hard for me to reach that as I am off-line most time). My tip is to add at Index: "Vzorec: zarovnánà podle symbolu" (probably something like "Formula: aligning along a symbol") I use a Czech version) and to the same page as "aligning formulas to the left, right, centered" please add the following paragraph (please correct my English): TIP: Aligning A Series Of Formulas Along Equal Sign To align several formulas along the = sign, you can use a matrix. Follow the example: (Note the "{}" brackets around the equal sign.) matrix{ alignr sin^2 x + cos^2 x#{}={}#alignl 1 ## alignr cos^2 x #{}={} #alignl 1 - sin^2 x } In Czech: TIP: Jak zarovnat nÄ›kolik rovnic pod sebou podle rovnÃtka Chcete-li zarovnat nÄ›kolik rovnic pod sebou podle rovnÃtka, použijte k tomu matici. Postupujte podle následujÃcÃho pÅ™Ãkladu: (VÅ¡imnÄ›te si složených závorek kolem rovnÃtka.) matrix{ alignr sin^2 x + cos^2 x#{}={}#alignl 1 ## alignr cos^2 x #{}={} #alignl 1 - sin^2 x }
OOPS! Please reassign from "How To" to "Online help"
I'll add this to the FAQ area, then assign it to the Online Help component. Thanks.
I have added this to the User FAQ area. Please find it located here: http://documentation.openoffice.org/user_faq/formula/022.html Thanks for the entry. I am going to put this into the Online Help category now.
I am afraid there are two overtypes. Please replace ALIGN1 with ALIGNL.
The faq question has a typos and should be changed to "How do I align several formulas along the '=' sign?"
Repaired the faq typos reported in the above two entries in both the user_faq and faqs areas.
added the example to file smath/01/03090700.xhp in CWS hcshared10
found on index page "formatting in OOo Math", in master m227 -> closed
Sorry, wrong window. Found this in hcshared10, not in m227 master
fixed in CWS
Please verify in CWS hcshared10 index page "formatting in OOo Math"

http://documentation.openoffice.org/user_faq/formula/022.html does not/ no longer/ exist(s)... Here is a new, or related, problem: In Misalign.odt, the same formula was pasted in different paragraphs. It aligns correctly with cc, ee, ff, but not with aa or bb --apparently, because these are numbered.

The FAQs were moved to the OOo Wiki. Find this FAQ at http://wiki.services.openoffice.org/wiki/Documentation/FAQ/Formula/How_do_I_align_my_equations_at_the_equality_sign%3F Please submit separate issues, one for each bug that you discover. If the issue is with the documentation, the "documentation" is the right component to select. If the issue is with the Math program code, then that is something the documentation authors cannot change. "Formula editor" is then the correct component for the issue. For the outdated links in the web page, the "website" or the "www" component should be used.
