Here is a much more complex formula: $$ \left(\sqrt{2}\right)^2=2 $$ and a very complicated proof: \begin{eqnarray*} 0 & \leq & (a-b)^2 \\ 0 & \leq & a^2-2ab+b^2 \\ ab & \leq & \frac{a^2+b^2}{2} \end{eqnarray*} Here is a complete \tex{\LaTeX} block: \tex{ \textbf{Pythagoras'theorem} states that: $$ \forall p,q \in \mathrm{\mathbf{N}}, \left( \frac{p}{q}\right)^2 \neq 2 $$ } \section{Other commands} Pointer to a \page{silly subpage}{ \title{Subpage!} This is empty.
