I'd like to rotate and mirror text left-right in Math.SE, as plain text or inside formulae. What I tried is from a TeX post or this one like:
$\require{rotating}$
$\require{graphicx}$
$\rotatebox{180}{Text}$
but all I get is
$\require{rotating}$ $\require{graphicx}$ $\rotatebox{180}{Text}$
If possible, I'd prefer a solution that does not use special charactes like $\forall$ ($\forall$
) for an unside-down $A$.
Combinations of rotations of 180° and mirror about vertical axis will do for me.
