I am using \boxed
to place emphasis on important equations in an assignment I am typing up, and would like to give the final answer a bit of extra emphasis. I'm using \begin{equation} ... \end{equation}
to number each line, so that I can put in references in the text.
There are some very nice looking boxes in the answers to Attractive Boxed Equations and framed equations, but both rely on colour, when I have a black and white printer. I was thinking of a double line around the final equation, but I'll take other answers if they are easier to code or look better.
I would love it if either the balanced boxes or the full width boxes were incorporated into the answer, but this is optional. It is a class assignment that the TA will look at for all of 10 minutes, not a publication.
Minimal Working Example:
\documentclass[letterpaper]{article}
\usepackage{kpfonts}
\usepackage{amssymb,mathtools}
\begin{document}
\begin{equation} \frac{M}{R} \propto R^2 \rho \end{equation}
\begin{equation} \label{eqn:density} \boxed{ \rho \propto \frac{M}{R^3} } \end{equation}
\end{document}
Best Answer
You can use the predefined boxes from the
fancybox
package, which you can wrap around equations via theempheq
package:This gives
Note that the definition of
\raisedshadowbox
contains a fudge factor of 0.6ex for the vertical offset correction. I don't know what this compensates for, but it does seem to work across different font sizes, line heights as well as\shadowbox
,\fboxsep
and\fboxrule
settings.
