What Does LaTeX Mean?
LaTeX is a document preparation system for typesetting. It is the de facto standard for the communication and publication of documents in the scientific community and is widely used by mathematicians, scientists, engineers, linguists and researchers. The system makes it easy to integrate complex mathematical formulas, equations, bibliographies and indexes into a document.
Techopedia Explains LaTeX
LaTex is a package that allows users to use the TeX typesetting program as the formatting engine. TeX typesetting is designed to document complex mathematical notations, text and formulas. That is why LaTeX is best suited for technical journals, reports, books and slide presentations. A LaTeX output is usually in a device-independent file format, which can then be exported to postscript or PDF.
