\noindent 
When using \LaTeX\ , you can drop a tex file into a problem by invoking the pictex and graphic package. The code in the preamble is:


\bigskip

\hspace*{.5in}$\backslash$usepackage\{pictex\}

\bigskip

\hspace*{.5in}$\backslash$usepackage[pdftex]\{graphicx\}




\vspace{.5in}

\prob{Consider the graph of $y = f'(x)$

\bigskip

\centerline{ \input testpict1.tex }

\bigskip



\bigskip

State all the intervals where $f(x)$, the original function, is increasing.

\vspace{.5in}


State all the intervals where $f(x)$ is decreasing.


\vspace{.5in}

Draw an approximate graph of $y = f''(x)$.  Indicate your scales.

\vspace{2in}



State all the intervals where $f(x)$ is concave up.
}  % end prob






\vspace{.5in}


The above graph was included in the file with the following code:

\bigskip

\hspace{.5in}$\backslash$centerline\{ $\backslash$input testpict1.tex \}


\bigskip

\noindent
To drop a jpeg into a \TeX\ document you should use the following code:

\bigskip

$\backslash$centerline\{


$\backslash$includegraphics[scale=.5]\{petemarsh.jpg\}


\}  \% end center


\bigskip

\noindent
But the formatting of a jpeg is difficult.  See the following.

``A find in 1984 in Lindow Moss, Cheshire, adds a new dimension
to the picture of interest in new places.  Workmen watching
a peat cutting machine found parts of a human body
preserved in the water logged peat about 0.7 metres ($2{1\over 4}$ feet)
below the present surface.  Excavations...revealed that the 
body, which was that of a man, had been garroted and then
dumped on the surface of the bog in a shallow pool.
Details of the stratigraphy in which the body was found,
and preliminary radiocarbon dates, suggest that
Lindow Man, or {\it Pete Marsh} as he is affectionately known
to those who found him, was executed some time towards
the end of the first millennium {\sc bc} or early first
millenium {\sc ad}.''
