Instructions for using LaTeX on your personal computer.

1. Download a program that transform LaTeX formulas into images.
   • For Windows, try MiKTeX.
   • For Unix, try these packages of MiKTeX.
   • For Mac, try MacTex.
   
   
2. You can create a LaTeX file with any editor (I use vi), but some people prefer to edit their source file
   and process it with the help of an interface.
   For Windows, you case use TeXworks, which now comes with MikTeX.
   Or you can use TeXmaker, which also works with Unix or Mac.
   
   The command "pdflatex" processes the LaTeX file and creates a PDF file.
   If you can't open the PDF file from within TeXmaker, try to open this PDF file directly.
   
   
   
3. Copy the sample document samplefile.tex to your computer. Open it under TeXmaker.
   • Click "PDFLaTeX".
   • Click "View PDF".
   The result should be similar to the file samplefile.pdf.
   
   
4. Save a copy of the document samplefile.tex under a new name (say, exercise.120106.tex).
   Modify this new file, preferably one small change at a time. After each change:
   • click "PDFLaTeX";
   • click "View PDF";
   • if you're happy then save the modified file.
