In LaTeX, how do I represent a differential equation?

To represent a differential equation in LaTeX, you can use the `\dfrac{d}{dx}` command to represent the differential operator, and you can use the `\text{ }` command to add text or variables to the equation. For example, the following code: Copy code `\dfrac{d}{dx} \left( x^2 \right) = 2x` will produce the following output: $$\\dfrac{d}{dx} \\left( x^2 \\right) = 2x$$ You can also use the `amsmath` package to use the `\frac{d}{dx}` command, which will produce a slightly smaller differential operator. For example: Copy code `\usepackage{amsmath} \begin{equation} \frac{d}{dx} \left( x^2 \right) = 2x \end{equation}` will produce the following output: $$\\frac{d}{dx} \\left( x^2 \\right) = 2x$$
