LaTeX PARTIALS

tex document:\documentclass[12pt]{article}\usepackage{amsmath}\title{\LaTeX}\date{}\begin{document}\maketitle [[partial1]][[partial2]]\end{document}

partial1:\LaTeX{} is a [[x]] for the \TeX{} typesetting program. It offers programmable desktop publishing features and extensive facilities for automating most aspects of typesetting and desktop publishing, including numbering and cross-referencing, tables and figures, page layout, bibliographies, and much more. \LaTeX{} was originally written in [[y]] by [[z]] and has become the dominant method for using \TeX; few people write in plain \TeX{} anymore. The current version is \LaTeXe.

partial2: \begin{align} E &= mc^2 \\ m &= \frac{m_0}{\sqrt{1-\frac{v^2}{c^2}}} \end{align}

variables:x = "document preparation system"y = 1984z = "Leslie Lamport"
