PhDP Posted September 30, 2007 Share Posted September 30, 2007 I learned it here. You mean, writing equations with LaTeX ? Or writing documents with LaTeX ? I learned to write documents with LaTeX by myself, I'm not an expert but I'm good enough to write articles with it, it's really much better than Microsoft Word. I use MiKTeX + TeXnicCenter.
