Unfortunally no good math manual exists for ConTeXt, but one can use
(nearly) all plain TeX commands.

Your plain TeX version works, but how about this:
(ConTeXt used to count, noalign doesn't need a(n extra) \hbox{})
\placeformula
\startformula
\eqalignno{
\sin^2 x &= 1-\cos^2 x & \formulanumber[sin]\cr
\noalign{and also}
\cos^2 x &= 1-\sin^2 x & \formulanumber[cos]\cr
}\stopformula
or alternative:
\placeformula[cos-sin]
\startformula
\eqalignno{
\sin^2 x &= 1-\cos^2 x & \formulanumber[sin2]{a}\cr
\noalign{and also}
\cos^2 x &= 1-\sin^2 x & \subformulanumber[cos2]{b}\cr
}\stopformula
Then you can refer to these equation by using:
\in[sin] produces 1
\in[cos] produces 2
\in[cos-sin] produces 3
\in[sin2] produces 3a
\in[cos2] produces 3b
