Quick Tips: Latex QED symbol

May 15, 2009 Latex

Some Latex document styles include a definition for a QED symbol (typically a box), but others do not.  If you are using a style that doesn’t come with one, you can quickly add your own definition of QED, just add:

\newcommand{\qed}{\hfill \mbox{\raggedright \rule{.07in}{.1in}}}

at the start of your document, and then you can use \qed to make the symbol wherever you need.
