LaTeX Plugin

I’ve just installed Pavel Holoborodko’s amazing QuickLaTeX WordPress plugin, and so now I can show fancy equations like this: |y – x| < \delta

And this: w_i = \frac{2}{\left(1-\xi_i^2\right)\,\left[P'_n(\xi_i)\right]^2}

And even super complicated stuff like this:

( \langle \sqrt{ \sqrt[3]{ \langle \frac{ e ^ { |f(y) – f(x)| < \pm \epsilon } } { |x - (y + z)| } \rangle } ^ 3 } \rangle ) ^Q_m

LaTeX is pretty expressive, and these examples are kinda addictive.

|x| = \left\{ \begin{array}{ll}<br /> x & \mbox{if $x \geq 0$};\\<br /> -x & \mbox{if $x < 0$}.\end{array} \right.<br />

Matrices look pretty good too. Let’s say I wanted to explain that the \emph{characteristic polynomial} \chi(\lambda) of the 3 \times 3 matrix

\left( \begin{array}{ccc}<br /> a & b & c \\<br /> d & e & f \\<br /> g & h & i \end{array} \right)<br />
is given by the formula \chi(\lambda) = \left| \begin{array}{ccc}<br /> \lambda – a & -b & -c \\<br /> -d & \lambda – e & -f \\<br /> -g & -h & \lambda – i \end{array} \right|<br />

Looks awesome. Have a look at David R. Wilkins’ Getting Started with LaTeX for some excellent examples, including some of the ones above.
