Re: Aligned numbered math formulas

[David Arnold]

All,

I am following this thread and I can report the same result as Holger.

\setupformulae[align=right]

\starttext

\placeformula[david]
\startformula
\eqalignno{%
left & right &  \formulanumber \cr
left & right &  \formulanumber \cr
}
\stopformula

\stoptext

Gives this result.

! You can't use `\halign' in math mode.
\eqalignno ...displ@y \tabskip \centering \halign
                                                  to \displaywidth {\hfil
$\...
l.10 }


May I ask how I can reference each of these equations separately in the
text? That is, how can I give a different label to each equation in the
alignment, then reference each one independent of the other?

Thanks.

\placeformula[david]
\startformula\eqalignno{
 left & right &  \formulanumber[david:a]{a} \cr
 left & right &  \formulanumber[david:b]{b} \cr
}\stopformula

Well, \in[david] should give "1.1" while \in[david:a] should give "1.1a".

Tobias,

Very nice.

Is there a setup that will typeset the labels as (1.1) and (1.1a)?

Not that I'm aware of, but I use \informula[foo] with

\def\informula#1{(\in[#1])}

Look up definereferenceformat, it's intended to do that more
cleanly :)
