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.
physics Options
Adding the physics extension to the packages array defines an
physics sub-block of the tex configuration block with the
following values:
MathJax = {
tex: {
physics: {
italicdiff: false,
arrowdel: false
}
}
};
- italicdiff: false
This corresponds to the italicdiff option of the physics LaTeX package to
use italic form for the d in the \differential and \derivative`
commands.
- arrowdel: false
This corresponds to the arrowdel option of the physics LaTeX package to
use vector notation over the nabla symbol.
Note, that the physics extension does not implement the notrig option.
