Introduction to LaTeX's argmin command

LaTeX's argmin command allows you to typeset the "argmin" operator, which is commonly used in mathematics to denote the argument that minimizes a given function.

To use the argmin command, simply type \argmin in math mode. This will produce the symbol "arg min" with a subscript placeholder.

For example, to typeset the argmin of a function f(x), you would write:

$$
\argmin_{x} f(x)
$$

This would produce the following output:

$$ \argmin_{x} f(x) $$

You can also use the argmin command in inline math mode, by enclosing it in $ delimiters. For example:

The value of x that minimizes f(x) is $\argmin_{x} f(x)$.

This would produce the following output:

The value of x that minimizes f(x) is $\argmin_{x} f(x)$.

Conclusion

The argmin command is a useful tool for typesetting mathematical expressions that involve minimization. By using this command in your LaTeX documents, you can achieve a professional and polished look for your mathematical content.
