 I would like to create a macro that defines a display formula, and then 
 redefine the same macro such that the redefinition includes the original 
 display formula followed by another display formula.  Here is my attempt.
 
 \def\foo{\startformula a = b \stopformula} \foo
 \edef\foo{\foo \startformula c = d \stopformula} \foo
 
 This fails, and I would appreciate help in getting this to work.


Your example works for me when I process it with mkiv but I would use a token 
list and not a macro to store the content.

\starttext

% macro

\def\foo{\startformula a = b \stopformula} \foo

\blank[2*line]

\edef\foo{\foo \startformula c = d \stopformula} \foo

\blank[2*line]

% token list

\newtoks\mytoks

\appendtoks
  \startformula a = b \stopformula
\to \mytoks

\the\mytoks

\blank[2*line]

\appendtoks
  \startformula c = d \stopformula
\to \mytoks

\the\mytoks

\stoptext
