\begin{itemize}
\item Consider
\[
F = \frac{1}{2}\, {\twentysy \int}_{\Omega} 
\left( \nabla\varphi \right)^2 d^3 \underline{x}
\]
where $\varphi$ is defined over a region $\Omega$ in $d$
dimensional space --- $d=2$ in text as one can draw.

\item $\varphi$ is fixed $=f$ on boundary $\partial\Omega$ of
$\Omega$ (Figure~FEM~1)
