How to typeset argmin and argmax in Markdown?


Typesetting argmin and argmax in Markdown for Stunning Equations

Ever needed to express the argument that minimizes or maximizes a function in your Markdown document? Look no further than the power of LaTeX, a powerful tool for typesetting mathematical expressions, which is supported by many Markdown editors.

The Problem:

Markdown, while great for basic formatting, lacks native support for complex mathematical symbols like argmin and argmax. This can be a hurdle when you need to represent these concepts in your writing.

The Solution:

LaTeX to the rescue! You can seamlessly embed LaTeX code within your Markdown using dollar signs ($) for inline equations or double dollar signs ( $ ) for displayed equations.

Example Scenario:

Let's say you want to express the following:

"The argument x that minimizes the function f(x) is given by argmin f(x)."

Original Code:

The argument x that minimizes the function f(x) is given by argmin f(x). 

Enhanced Code with LaTeX:

The argument x that minimizes the function f(x) is given by $argmin f(x)$.

Output:

The argument x that minimizes the function f(x) is given by argmin f(x).

Explanation:

  • $argmin f(x)$ is the LaTeX code for argmin f(x).
  • The dollar signs ($) encapsulate the LaTeX code, telling the Markdown renderer to interpret it as a mathematical expression.

Let's Explore More:

You can also typeset argmax using the same approach:

The argument x that maximizes the function f(x) is given by $argmax f(x)$.

Output:

The argument x that maximizes the function f(x) is given by argmax f(x).

Adding Constraints:

You can even specify constraints within the argmin or argmax expressions:

The argument x that minimizes the function f(x) subject to the constraint g(x) = 0 is given by $argmin_{g(x) = 0} f(x)$.

Output:

The argument x that minimizes the function f(x) subject to the constraint g(x) = 0 is given by argmin_{g(x) = 0} f(x).

Key Takeaways:

  • LaTeX is your friend for typesetting advanced mathematical expressions in Markdown.
  • Use dollar signs ($) for inline equations and double dollar signs ( $ ) for displayed equations.
  • Familiarize yourself with basic LaTeX commands for argmin, argmax, and other mathematical symbols.

Resources:

  • Overleaf: A great resource for learning LaTeX basics.
  • MathJax: A JavaScript library that enables LaTeX rendering in web browsers, often used in Markdown editors.

With this knowledge, you can confidently express argmin and argmax with elegance in your Markdown documents. Enjoy typesetting your mathematical ideas!
