My understanding is that
\[...\] is preferred to
$$...$$ for delimiting displayed equations in latex. See this discussion on tex.stackexhange for the reasons why.
However, math.stackexchange does not seem to support
\[ ...\], for example:
[ a^2 + b^2 = c^2 ]
vs $$a^2 + b^2 =c^2.$$
and the semi-official MathJax tutorial thread explicitly says to use
- Is there a specific reason for using
- Does MathJax just not support
\[...\]and this would require semi-major back end changes?
- Would support for
\[...\]be possible to add?
