physics

The physics extension implements much of the LaTeX physics package, which defines simple, yet flexible macros for typesetting equations via:

• Automatic bracing

• Vector notation

• Derivatives

• Dirac bra-ket notation

• Matrix macros

• Additional trig functions and other convenient operators

• Flat fractions and other useful miscellaneous math macros

See the documentation for the LaTeX package for more information.

This package is not autoloaded, due to the fact that it redefines many standard macros, so you must request it explicitly if you want to use it. To load the physics extension, add '[tex]/physics' to the load array of the loader block of your MathJax configuration, and add 'physics' to the packages array of the tex block.

window.MathJax = {
  loader: {load: ['[tex]/physics']},
  tex: {packages: {'[+]': ['physics']}}
};

Alternatively, use \require{physics} in a TeX expression to load it dynamically from within the math on the page, if the require package is loaded.
