It works in many cases that item content ends with words. But it is not working if the item contents end with \stopformula. If I put \placeclosesymbol before \stopformula, then it is shown just after the last word.
Anyway, it works in most cases.

Thank you again.

Best regards,

Dalyoung

This is a simple proof.
\startformula
1+1=2.
\stopformula
\placeclosesymbol
\stopproof

\startproof
This is another simple proof that ends with a formula
\startformula
1+1=2.

\startproof
\startitemize[n]
\item first line.
\item Here is an example.
\startformula \cosh x + \sinh x = e^x,~~\cosh x - \sinh x = e^{-x}	\stopformula
The next formula is following:
\startformula\startalign
\NC\sinh (x + y) \NC= \frac{e^{x+y} - e^{-(x+y)}}{2} \NR
\NC 		\NC = \frac{e^x e^y - e^{-x}e^{-y}}{2}	\NR%\$
\NC 	\NC = \frac{(\cosh x + \sinh x)(\cosh y + \sinh y) - (\cosh x - \sinh x)(\cosh y - \sinh y)}{2} \NR
\NC 	\NC = \sinh x \cosh y + \cosh x \sinh y         \NR
\stopalign \stopformula
\placeclosesymbol

\stopproof
