# How can I use $\LaTeX$ symbol \Perp (from pxfonts/txfonts) in mathjax?

The title says it all: How can I use math symbol \Perp (like $\perp$ but with two verticals) from txfonts/pxfonts in mathjax? It is sometimes used in probability to denote independence.

• $\perp\!\!\!\perp$ = $\perp\!\!\!\perp$ – Surb Apr 24 '17 at 5:36
• Thanks! Let us try: $\newcommand{\Perp}{\perp\!\!\!\perp}$ $\Perp$ – kjetil b halvorsen Apr 24 '17 at 6:05
• This one: $\perp\,\!\,\!\,\!\,\!\,\!\,\!\,\!\!\!\!\perp$ is even nicer but more complicated: $\perp\,\!\,\!\,\!\,\!\,\!\,\!\,\!\!\!\!\perp$ – Surb Apr 25 '17 at 13:04

You could use \unicode{x2AEB}, but note that this character is not in the MathJax TeX fonts, so it would rely on the user having a font with this character installed on their system. The STIX fonts are one such set of fonts, and if you are authoring your own pages, you could configure MathJax to use the STIX-Web font so that it would be available.
