This guide works on all computers having access to the web and all users with a FAS account. Especially, you don't need to have Mathematica installed on your machine.

1) Telnet to fas. 2) Grab remote.m from the webserver 3) Start mathematica 4) Load in remote.m 5) Enter Mathematica code. The graphic output is in a PS file test.ps and a GIF file test.gif 6) Publish it on your website or publish it as a PdF Document, or simply print it out with "lpr test.ps".

Example:

lynx -dump http://www.math.harvard.edu/computing/math/remote.m>remote.m

ParametricPlot3D[{Cos[u]*Sin[v],Sin[u]*Sin[v],Cos[v]+Log[Tan[v/2]]+0.2*u},
  {u,0,4*Pi},{v,0.04,1.0}, Boxed->False,Axes->False]

Publish the picture on your website

1) If no directory public_html exists create it with
ice%mkdir public_html

2) Copy the picture test.gif into public_html:
ice%cp test.gif public_html

3) Make the picture accessible for the world:
ice% chmod 755 public_html; chmod 755 public_html/test.gif

4) Point your webbrowser on your machine to the picture on your website
http://www.fas.harvard.edu/~yourloginname/test.gif

If access is denied, you need to make your home directory accessible. This can be done with
ice%cd; cd ..; chmod 755 `whoami`;

Publish it as a PDF document

Edit a file picture.tex containing the text

\documentclass{article}
\usepackage[dvips]{graphics}
\title{Math 21a, Solution of the homework problem}
\begin{document}
\maketitle
My solution to the Homework problem  \\
  \includegraphics{test.ps}
\end{document}

Process the LateX file, translate it into PS and then to PDF and make it public.

Depending on your operating system configuration, see either the pdf document http://www.fas.harvard.edu/~yourloginname/picture.pdf directly in the web browser, or using an external PDF viewer:
