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}   x & \mbox{if $x \geq 0$};\\   -x & \mbox{if $x < 0$}.\end{array} \right.

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

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

    A house is just a place to keep your stuff while you go out and get more stuff.

    Dis quelque chose, puis le titre du contenu de l’article n’est pas conforme à l’ah.
