For the benefit of other novice users here, the following is how I got pdfscreen to work making slides the way I needed them.  It may help someone else, so here it is:

there are two other files that go with this one:
<http://www.csun.edu/~kg46825/troy/trapz_error_steps.pdf>
<http://www.csun.edu/~kg46825/troy/friburg_template.pdf>

a couple of other notes:

* I had to set the footers in the first slide environment
* When I reset a footer with \cfoot, it affects the previous slide

% next 2 lines: these adjustments put the footer where I want

% this slide has text on the left and a figure on the right
\begin{slide}
\parbox{.4\linewidth}{
\begin{itemize}
\item Trapezoidal integration error bound is $(Nh)\frac{h^2}{12}f^{''}_{max} \approxeq 9 \times 10^{-10} km^2/s^2$
\begin{itemize}
\item $(Nh)$ is about 96 minutes
\item $h$ is one RTI (1/8 sec)
\item $f$ is $(\vec{V}\cdot\vec{a})$, so $f^{''}_{max}$ is roughly $12 \times 10^{-11} km^2/s^5$
\end{itemize}
\item $\frac{9 \times 10^{-10} km^2/s^2}{17 km^2/s^2} \approxeq 5 \times 10^{-11}$ at one RTI (8 steps per second), which bounds the plot to the right.

\cfoot{\colorbox{white}{\bf\sffamily\Large C-\thepage (Appendix)}}

\begin{itemize}
\item The change in orbital energy for a two-body conic:
$\Delta E (t) = \int_0^t \vec{V}_{w/SOI}(\tau)\cdot\vec{a}_{SOI}(\tau) d\tau$
\item Assume that the influence of $\vec{a}_{SOI}$ is small enough to be linear
$\vec{V}_{w/SOI}(t) = \vec{V}_{no-SOI}(t) + \int_0^t \Phi (t,\sigma) \vec{a}_{SOI}(\sigma) d\sigma$
\item Throw out second-order terms to arrive at the approximation
$\Delta E (t) = \int_0^t \vec{V}_{no-SOI}(\tau)\cdot\vec{a}_{SOI}(\tau) d\tau + \underbrace{\int_0^t \int_0^t \left[ \Phi (\tau,\sigma) \vec{a}_{SOI}(\sigma)\right] \cdot\vec{a}_{SOI}(\tau) d\sigma d\tau}_\text{second-order; throw away}$
