| Here we use a math block that contains nothing but definitions in
| standard TeX format. It is enclosed in a DIV that doesn't display, so
| that there are no extra spaces generated by having the extra
| mathematics in the text.
|
| The first macro makes it easy to display vectors using \<x,y,z>
| the second uses \newcommand to create a macro
|
|-->
<div style="display:none">
\(
\def\<#1>{\left<#1\right>}
\newcommand{\CC}{\mathbf{C}}
\)
</div>
<p>
This page uses two different methods to define macros: either putting them
in JavaScript notation in the MathJax configuration, or in TeX notation in
the body of the document.
</p>
<p>Some math that used the definitions:
\[
f\colon\RR\to\RR^3 \hbox{ by } f(t)=\< t+1,{1\over 1+t^2}, \sqrt{t^2+1} >
\]
and
\[
\{\,z\in\CC \mid z^2 = \bold{\alpha}\,\}
\]
