Communicating complex equations via email poses challenges, especially with complicated partial differential equations (PDEs). Many users prefer attaching PDFs containing the equations or using LaTeX for simpler equations. However, this method can hinder the ability for others to edit the content easily. Some individuals draft responses by hand, scan them, and send them as PDFs, while others suggest using LaTeX to create images of equations for insertion into emails. There is interest in WYSIWYG (What You See Is What You Get) LaTeX tools for easier formatting, with Scientific Word being a notable option, though it is not yet available for Linux. Alternatives like eqascii allow for rendering equations in plain ASCII format using a LaTeX-like syntax, enabling easy copy and paste functionality.
