ams
The ams extension implements AMS math environments and macros, and
macros for accessing the characters in the AMS symbol fonts. This
extension is already loaded in all the components that include
the TeX input jax, other than input/tex-base
. See the list
of control sequences for details about what commands
are implemented in this extension.
To load the ams extension explicitly (when using
input/tex-base
for example), add '[tex]/ams'
to the
load
array of the loader
block of your MathJax configuration,
and add 'ams'
to the packages
array of the tex
block.
window.MathJax = {
loader: {load: ['[tex]/ams']},
tex: {packages: {'[+]': ['ams']}}
};
Alternatively, use \require{ams}
in a TeX expression to load it
dynamically from within the math on the page, if the require
extension is loaded.
