# Input:

In LaTeX, how do I represent a differential equation?

# Output:

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} $$\frac{d}{dx} \left( x^2 \right) = 2x$$ will produce the following output: $$\\frac{d}{dx} \\left( x^2 \\right) = 2x$$
