On this answer, I tried using the LaTeX formula formatting to prettify it.

However, formula formatting no longer seems to work.

For instance, I wrote $ \Delta V $ into it and get the text you see, while I expected the capital version of the Greek letter "Delta" followed by the letter "V".

When and why did this stop working. What do I use instead?

  • You could just use the ascii symbols for Δv

  • @Richard nitpick: Δ is only in unicode, not ASCII. Jun 25, 2015 at 18:59

    @CodesInChaos - I pride myself on not knowing the difference.

As far as I know, it never worked on this SE site. It's something that's enabled on a per-site basis by Stack Exchange. We don't really need it like other sites (e.g. Math), so it's not enabled here.

  • That's correct.
