Link to math blocks

[patrick-egenlauf]

I am using the MathJax library to write math equations both in math blocks and inline. I would like to insert a link to an equation (block) in the text. Is this possible, and if not, would you consider adding this as a new feature?

You can always add a headline or div with an id around your block that you want to link to, or preface it with a headline. Other than that, directly linking to MathJax blocks is something that should be implemented by MathJax itself ☺️

<div id="my-anchor" markdown>

$$
\cos x=\sum_{k=0}^{\infty}\frac{(-1)^k}{(2k)!}x^{2k}
$$

</div>

Thanks for the quick reply. I tried it, but then the equation doesn't render properly (dollar signs and everything in between is displayed as plain text).

I'm also not familiar with html, so how can I link to this block in my text, assuming it works?

Sorry, I forgot to mention, that you need to add the md_in_html extension to mkdocs.yml

markdown_extensions:
  - md_in_html

This is already possible with MathJax via \tag and/or \label inside the equation. See for example the MathJax documentation about automatic equation numbering or this stackexchange post under Tags & References or Equation numbering.
