\pagestyle{empty} in the
preamble of your LaTeX source file. If one the other hand,
you wanted to suppress the page number on one page but not
on the others, then use \thispagestyle{empty}.
Typically, this might be done on the first page.
\pm.
\center environment, the \flushleft
environment positions text on the page. You may use it to avoid
paragraph indents. There is also a \flushright environment.
Recall that in the
LaTeX graphics assignment from last class,
you worked with an Encapsulated PostScript File
(file-type EPSF) called golfer.ps. We used the LaTeX graphics package
epsf, which was designed to work with the dvips driver.
Since you may want to do similar work on another system, which may use a different
driver for converting dvi files, we will also look at the package called
graphicx and at the package called epsfig. Open a
terminal window and a text editor, and then use your mouse to copy the following
LaTeX source code into your editor.

This is a test of the graphicx postscript graphics package.
Some people have a \rotatebox{25}{slanted view} of the world.
\reflectbox{Is this secret writing or what??}
We can both rotate and adjust the dimensions of the included graphics
by commands in the graphicx package. Here is an example.
Can you tell whether the width was adjusted before or after the
rotation?
\begin{figure}
\begin{center}
\includegraphics[angle=30,width=4in]{golfer.ps}
\end{center}
\end{figure}

graphicx-test.tex. Make sure that the file
golfer.ps is in the same directory as graphicx-test.tex.
Then run latex graphicx-test and use dvips to convert
the resulting dvi file to graphicx-test.ps. Print this
file and turn in hard copy by the end of class.
Remark. To conserve disk space, you
should remove the final PostScript file, and you may want to remove the other
files produced by LaTeX as well, saving only the source file.
Of course, you may start on the homework during class if you have time.
epsfig-test.tex. Before you run
latex on the new file, make sure that the PostScript
files that you want to use have been moved to the same directory.
View your file by using dvips epsfig-test -o epsfig-test.ps and
then use your PostScript viewer to look at the typeset file. For
exaple, if you are on clam server use the command
ghostview epsfig-test.ps. On a PC you should
be able to view PostScript by using YAP (Yet Another Previewer).

This is a test of the epsfig postscript graphics package.
Here is an example of an included graphic floated as a
centered box with a height of $y$ inches and a width
of $x$ inches.
%You should choose suitable numbers as values to substitute for <x> and
%<y> here and in the commands below. See the example further down.
%(In particular, there should be no angle brackets in the argument to \epsfig.)
\begin{figure}
\begin{center}
\epsfig{file=<your-filename1.ps>, height=<y>in, width=<x>in}
\end{center}
\end{figure}
We can both rotate and adjust the dimensions of the included graphics
by commands in the epsfig package. Here is an example.
Can you tell whether the width was adjusted before or after the
rotation?
\epsfig{file=<your-filename2.ps>, height=4in, width=3in, angle=45}
\end{document}
After viewing the results of your first run, see what the effects are when you change the height or width or angle. What happens if you take out either of the keyvalues height=<something> or width=<something>?
When you have things working to your satisfaction, write up a LaTeX document that displays the effects that you can get with epsfig. You should have at least three included figures. I suggest that you keep the dimensions of the figures modest to avoid creating a huge PostScript file. Please hand in the typeset version of your document at the beginning of our next class meeting.
If you have done all the in-class activities suggested above, and there is still time left, here are some other activities you can do.
