As a challenge to other mathematicians, Johann Bernoulli posed the orignal problem that lead to the curve known as the brachistochrone.[1]

[edit] Some examples of math markup

{{9x^2 \over x+2} \over {6x \over x^2+x-2}}

\int_{a}^{b} f(x) dx

[edit] Tip, courtesy of Samw

The kappa renders inconsistently: Suppose \tau_d \simeq \delta^2 / \kappa where κ is the thermal conductivity.

This is better: Suppose \tau_d \simeq \delta^2 / \kappa where \kappa \; is the thermal conductivity.

[edit] Big S

The action, denoted by \mathcal{S}, is the time integral of the Lagrangian:

S = \int L\,dt.
\mathcal{S} = \int L\,\mathrm{d}t.

[edit] Sed script

This is here mostly so I do not loose it, but feel free. It is probably of pretty narrow utility. Here is a sed script that edits a local copy of Special:Linksearch to generate a page of links for use with the external editor.
