It's sort of a side effect of lack of control over what tex does (i can imagine a solution i.e. lap left or right depending on the location but that would then have to be under control of (say) \matheqoverflowmode or so (0 = normal, 1 = lap back into the text, 2 ...). I will have a look at it but it's not a short term solution for your problem the too wide formula, unless you do a local \setupformulas [distance=-2cm] or so).

[NTG-context] Weird position of equation numbers for long equations
Hi,
I suspect that the equation numbering in attachment
(eq-with-chapter.png) is wrong. Shouldnt't the number be positioned on
the right (not on the left)? And in case that this positioning on the
left is intentional: is there any way or setting to force the equation
number to be moved to the right?
In any case I suspect that the equation in question could somehow be
squeezed into the available space in one line. What's the best trick
to squeeze the equation into a single line? Some kind of \hbox to
0pt{\hss [content] \hss} trickery or does there exist something
better?
Minimum problematic example:
\starttext
\placeformula
\startformula
\dorecurse{28}{a+}
\stopformula

Thank you,
Mojca

Make a small angle approximation and express your angles in radians.
This simplifies the equation significantly... ;-)
