For each one of the problems used in one of your weeks (in a Problem
Set, in class, or in a quiz):

1. Create a .tex file containing the latex code for this problem and
its solution.  This file is just a latex fragment and shouldn't
include any other commands not related to the problem (like
\begin{document}).  You should just name your file after where it
appeared this term (Spring 02).  For example, ps6-5.tex

   1a. The file should start with a \problemdata macro, indicating
where the problem came from and has been used.  You probabl

        \problemdata       % Takes 5 *mandatory* arguments
        {variance-6}             % latex-friendly label for the prob.
        {variance, expectation}  % The topic(s) of the problem content.
        {Velleman}               % Source (if known)
        {S98 PS11-7; F97 PS11-8} % Usage (list ones you are aware of).
        {Theory Pig, S02}        % Last revision info (author, date).

This will be followed by a problem in the standard form:

  \begin{problem}      
  This is a problem!
 
  \begin{problemparts}
  \problempart This is the first part

  \solution{
    And it was solved.
  } 

  \problempart This is the second part

  \solution[\vspace{2cm}]{     % optional spacing argument!
    Here is another solution 
  }

  \end{problemparts}
  \end{problem}



For an example, check file ps6-5.tex under freshRepository/asymptotics.


2. To check the LaTeX code of your problem, copy file
       freshRepository/driver.tex
into your working directory 
       cp freshRepository/driver.tex ~/temp
and latex it
       pdflatex driver
It will ask for the name of the file of your problem and whether you
want the solutions included or not. At the end,
       driver.pdf
will contain the final output of your LaTeX code.


3. After you have check the code, put the file in the appropriate
subdirectory under the directory 
        /toc/a/class/6.042/spring02/freshRepository
   
   3a. If your problem matches more than one topics and should therefore
       be placed in more than one subdirectories, put it only in one and
       use links in the other subdirectories. For example, if you file  
                ps3-4.tex
       should be placed both in
                intro-logic
       and in
                sets
       copy your file into "intro-logic"
                cp ps3-4.tex freshRepository/intro-logic
       and create a link to it in "sets"
                ln freshRepository/intro-logic/ps3-4.tex freshRepository/sets/ps3-4.tex
       (first argument is the target of the link, second argument is
       the link name).
