'\boxed' Tex Command

The \boxed command in LaTeX is used to draw a box around a mathematical expression. This command is useful when you want to highlight a particular equation or when you want to draw attention to a part of an equation. Here's how you can use the \boxed command:

$$ \boxed{a^2 + b^2 = c^2} $$

This will draw a box around the equation a^2 + b^2 = c^2.

You can also use the \boxed command with other LaTeX commands to create more complex expressions. For example:

$$ \boxed{\frac{d}{dx}\left(f(x)\right) = f'(x)} $$

This will draw a box around the expression describing the derivative of f(x).

Another useful feature of the \boxed command is that you can change the color of the box. This is done using the color package. Here's an example:

\usepackage{color}

\begin{document}

$$ \boxed{\colorbox{yellow}{$a^2 + b^2 = c^2$}} $$

\end{document}

This will draw a yellow box around the equation a^2 + b^2 = c^2.

The \boxed command is a simple but powerful tool for drawing attention to mathematical expressions. With its ability to change colors and work in conjunction with other LaTeX commands, it can help add clarity and emphasis to your work.
