Re: [NTG-context] Problem with \leqalignno

2016-09-11 Thread Mingranina Gingranina
Dear Aditya, Otared, and Hans,
 Hello,

 Thank you all very much for your help. Your codes work fine. However when I use
 \setupformulas[location=right] the equation numbers apperar on the rightmost of
 the line, but with \setupformulas[location=left] the equation numbers
appear near
 the formulas and not on leftmost of the line. What should I do so
that in both cases
 the equation numbers appear near the formulas or with
\setupformulas[location=left]
 the equation numbers appear on the leftmost of the line?

 Thanks
 Mingranina

Hi Mingranina,

For displayed aligned formulas it is better to use \startalign…\stopalign, 
instead of the plain TeX construction \leqalignno.
Please have a look at the following:

Best regards: OK
%%% begin align-equations.tex
\starttext

\placeformula
\startformula
\startalign
\NC c^2 \NC= a^2 + b^2  \NR[+] 
\NC a^2 + b^2 \NC = c^2  \NR[+] 
\NC d^2 \NC = e^2\NR[+] 
\stopalign
\stopformula

\startsubformulas[eq:Rel]
\placeformula
\startformula
\startalign
\NC c^2 \NC= a^2 + b^2  \NR[eq:a] 
\NC a^2 + b^2 \NC = c^2  \NR[eq:b] 
\NC d^2 \NC = e^2\NR[eq:c] 
\stopalign
\stopformula
\stopsubformulas
The relations (\in[eq:Rel]) are divided into three parts, but (\in[eq:c]) is 
obvious.

\stoptext
%%% end align-equations.tex

Hello All,

I am trying to compile the following example (from
http://wiki.contextgarden.net/Math/Display) with context:

\starttext

\startformula
\leqalignno{c^2 &= a^2 + b^2  &\formulanumber{a} \cr

\stopformula

Am I doing something wrong? Any help would be gratefully appreciated.


How about:

\setupformulas[location=left]
\starttext

\startsubformulas
\placeformula[+] \startformula \startalign
  \NC c^2 \EQ a^2 + b^2 \NR[+]
  \NC a^2 + b^2 \EQ c^2 \NR[+]
  \NC d^2 \EQ e^2 \NR
\stopalign \stopformula
\stopsubformulas

\stoptext
