I was wondering if anyone could help me with a problem I'm having. I'm currently going through some math books that I want to read on my sony prs 600. Unfortunately it is in pdf format and the margins are quite excessive on it. I would like to remove the margins. But when I try to in Calibre, it becomes unreadable.

I would be willing to use a different format, but .pdf is the only electronic format freely available and the book has a lot of latex in it. And .pdfs seem to be the only type of document that can display latex text well.

I have attached the unconverted file.
Thanks
