I want to the tex files from PDF files. I have the PDF files that I get in Internet and have a lot of mathematics, so I want to convert PDF files into tex files. I researched in these forum, and following links may be related ,but I couldnt understand clearly. Is there some way to embed LaTeX source code in a PDF file? Embed link to an embedded file
Please teach me are there any ways, or teach me how to use.
