Code highlighting with pygments

Here’s some Haskell:

-- Factorial function
factorial :: Integer -> Integer
factorial 0 = 1
factorial n = n * factorial (n - 1)

-- QuickSort implementation
quicksort :: Ord a => [a] -> [a]
quicksort [] = []
quicksort (x:xs) = quicksort smaller ++ [x] ++ quicksort larger
  where
    smaller = [a | a <- xs, a <= x]
    larger  = [b | b <- xs, b > x]

Mathematical expressions

Testing inline math: \(E = mc^2\) and the quadratic formula \(x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}\).

Display math:

\[ \int_{-\infty}^{\infty} e^{-x^2} dx = \sqrt{\pi} \]

Another example:

\[ \nabla \times \mathbf{E} = -\frac{\partial \mathbf{B}}{\partial t} \]

TikZ diagram test

Here’s a simple TikZ diagram:

\begin{tikzpicture}
  \draw[->] (0,0) -- (4,0) node[right] {$x$};
  \draw[->] (0,0) -- (0,3) node[above] {$y$};
  \draw[domain=0:3.5,smooth,variable=\x,blue,thick] plot ({\x},{0.5*\x*\x});
  \node at (2,2.5) {$y = \frac{1}{2}x^2$};
\end{tikzpicture}

More complex TikZ

\begin{tikzpicture}[node distance=2cm]
  \node[circle,draw] (A) {A};
  \node[circle,draw] (B) [right of=A] {B};
  \node[circle,draw] (C) [below of=A] {C};
  \node[circle,draw] (D) [right of=C] {D};
  
  \draw[->] (A) -- (B);
  \draw[->] (A) -- (C);
  \draw[->] (B) -- (D);
  \draw[->] (C) -- (D);
\end{tikzpicture}

Emphasis and formatting

This is italic text and this is bold text. We can also combine both italic and bold.

Here’s some inline code within a sentence.

Footnotes

This sentence has a footnote². And this one has another³.
