MathJax test

Well, after discovering my long-lost yearbook and Physics olympiad "ten year series", I have decided to try solving some of those problems. Over some period of time.

However, it is easier to type than to write (mostly), so... I decided to look for some way of writing TeX on this. A Google search later, http://tex.stackexchange.com/questions/13865/how-to-use-latex-on-blogspot.

Here goes nothing...

It is obvious that $\sin^2 \alpha + \cos^2 \alpha = 1$ or that $e^{i\pi} + 1 = 0$. However, how does one show that

$$\oint_S E \cdot dS = \frac{Q_{\text{in}}}{\varepsilon_0}$$

is true?

[Afternote: I am impressed. It looks good.]
