<!--

|
| 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.
|
||
|

<script type="text/x-mathjax-config">

MathJax.Hub.Register.StartupHook("TeX Jax Ready",function () {
|
||
|
|
MathJax.Hub.Insert(MathJax.InputJax.TeX.Definitions.macros,{
|
||
|
|
cancel: ["Extension","cancel"],
|
||
|
|
bcancel: ["Extension","cancel"],
|
||
|
|
xcancel: ["Extension","cancel"],
|

|
|
cancelto: ["Extension","cancel"]

});

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