To create PDF documents with LaTeX, users can write text in a word processor like MS Word and use a LaTeX interpreter for equations, then paste the equations as bitmaps into the document. If Adobe Acrobat is properly integrated, users can convert the Word file to PDF. Alternatively, for a more LaTeX-focused approach, users can write their entire document in LaTeX, saving it with a .tex extension. This file can be compiled using pdflatex to directly generate a PDF. For those using LaTeX, it's recommended to use it for mathematically intensive documents, as it allows for comprehensive document creation beyond just equations. Additionally, Mac users can utilize the system-wide "save as PDF" feature available in OS X.
