Using a stylus to write math symbols on paper and transfer them to a computer
LaTeX simplifies creating polished documents since it manages formatting automatically. You only need to input the content. Another advantage is defining custom macros. For example, writing a derivative explicitly in math mode as dy/dx is straightforward, but you can use a macro like \df to achieve the same result. This saves typing effort—two characters instead of writing the full expression. If you prefer y'(x) over dy/dx, updating the macro definition resolves the change everywhere. I’ve used this to streamline my quantum mechanics lecture notes and multivariable calculus materials, making the writing process much smoother.
