+\begin{abstract}
+This paper gives several examples of typesetting very wide equations with {\upshape\LaTeX} in the {\upshape\texttt{asmeconf}} class~{\upshape\cite{lienhard2021}} using {\upshape\texttt{asmewide.sty}}.
+The style defines a the {\upshape\texttt{widetext}} environment, built on the 2021 release of {\upshape\texttt{cuted.sty}~\cite{tolucsis1}} from the
+{\upshape\texttt{sttools}} bundle~{\upshape\cite{tolucsis2}}, which is available from CTAN, \hrefurl{http://ctan.org}{ctan.org}.
+Significant hand-fitting around pagebreaks, floats, and footnotes is required to obtain good results. Users can change the source file to explore the behavior and limitations of the {\upshape\texttt{widetext}} environment. \textcolor{red}{Only the text in \textbf{red} in this document meant
+to be read---the rest is simply filler to aid in layout.}

+\section{Single Wide Equation on the Page}
+
+\textcolor{red}{Equation~\eqref{eqn:WT1} is an equation with a matrix that is too large to fit into one column. A multiline math environment will not help because the equation cannot be broken into parts that each fit into a column. The \texttt{widetext} environment solves the problem.}
+
+\textcolor{red}{A two-column wide figure, Fig.~\ref{fig:1}, has floated from a previous page to the top of this page, but does not interfere with the \texttt{widetext} material (a one column float would interfere).}

+\end{equation}

+\textcolor{red}{In this case, we have a pair of wide equations on the same page. The \texttt{widetext} environment cannot be used twice on the same page! To resolve the conflict, we remain in single column mode between the two equations.}

+\section{Spherical harmonics\label{sec:sph-har}}
+
+Without getting into the details, a regular function $f(\theta,\phi)$ on the surface of the unit sphere may be written
+\begin{equation}
+f(\theta,\phi) = \sum_{n=0}^\infty \sum_{m=-n}^n f_{m,n} Y_n^m(\theta,\phi)
+\end{equation}
+for $Y_n^m(\theta,\phi) = e^{i m\phi}P^{|m|}_n(\cos\theta)$, for $|m|<n$. The case $n=3$, $m=2$ (a \textit{tesseral harmonic}) is shown in Fig.~\ref{fig:tesseral}.
+
+These functions are orthogonal, with the normalization constant~\cite[App.~A]{stakgold}:
+\begin{equation}
+N_{m,n}=\int_0^{2\pi}\!\!d\phi\int_0^{\pi}\!\!d\theta \sin\theta\, \big|Y^m_n(\theta,\phi)\big|^2 = \frac{4\pi (n+|m|)!}{(2n+1)(n-|m|)!}
+\end{equation}
+
+If $f$ is independent of the azimuthal angle $\phi$, the solution appears in ordinary Legendre polynomials, $P_n$, rather than associated Legendre polynomials, $P^m_n$ ($P^0_n = P_n$):
+\begin{equation}
+f(\theta) = \sum_{n=0}^\infty f_n\, P_n(\cos\theta)
+\end{equation}
+The terms in this series are called \textit{zonal harmonics}.
