| | This page shows how to define macros that autoloads an extension | where those macros are implemented. | | The \cancel, \bcancel, \xcancel, and \cancelto macros are | all defined within the cancel extension, so we tie these | macros to the function that loads an extension, passing it | the name of the extension to load. | |-->

<p> This page makes \cancel
, \bcancel
, \xcancel
, and \cancelto
all be defined so that they will load the cancel.js
extension when first used. </p>
<p> Here is the first usage: (cancel{x+1}). It will cause the cancel package to be loaded automatically. </p>
