I'm framing certain elements in my document with the framed
and the empheq
- packages.
However, since i wanted a uniform way to just use one environment, i figured using tcolorbox
would be the easiest way to go. I defined my own box as
\newtcolorbox{mybox}[1][]{before=\centering, hbox, drop fuzzy shadow, enhanced, colback=white, sharp corners, colframe=red, fonttitle=\bfseries, title=#1, center title}
However now, i can't include displayed math in a lot of environments inside that new box! In my case, i usually get away with just using the align*
environment, but i didn't find anything on the internet, nor in the TcolorBox-Manual, that taught me how to add support for align*
(which i think i have to).
Can someone help me out?
MWE:
\documentclass{article}
\usepackage{tcolorbox, mathtools}
\tcbuselibrary{skins}
\newtcolorbox{mybox}[1][]{before=\centering, hbox, drop fuzzy shadow, enhanced, colback=white, sharp corners, colframe=red, fonttitle=\bfseries, title=#1, center title}
\begin{document}
\begin{mybox}
\begin{align*}
z &= r \cos \varphi + \Im r \sin \varphi = r e^{\Im \varphi}\\
r &= |z| = \sqrt{x^2 + y^2}
\end{align*}
\end{mybox}
\end{document}
