LaTeX is a typesetting system widely used for formatting mathematical and scientific documents, enhancing readability and presentation. It allows users to create complex equations and symbols, such as \mu, \alpha, and \tau, with improved clarity. For inline math, using itex and /itex is recommended, while tex and /tex are better for standalone equations. This system is particularly favored in academic and technical fields for its precision and versatility. Understanding LaTeX can significantly improve the quality of mathematical documentation.
