This is a test page of a test user.
Let us try MathJax:
The probability of getting \(k\) heads when flipping \(n\) coins is:
\[\begin{aligned} \dot{x} & = \sigma(y-x) \\ \dot{y} & = \rho x - y - xz \\ \dot{z} & = -\beta z + xy \end{aligned} \]

This is a greek symbol in the text: \(alpha\)
take this: \(x_1\)

equation comes here

Eq.2.

Why a test page?

Why why?

this is a test for a equation.

\[\begin{aligned} E=mc^2 \end{aligned} \]

Eq. 2

http://www.sitmo.com/gg/latex/latex2png.2.php?z=100&eq=\frac{SI%20k%20c%20rt\sqrt{-1}}{b}

Why test

{FORMULA(2)}
e=mc^2
{FORMULA}

this is a code hblock:

void foo()
{
foo_is_cool();
}

\[\begin{aligned} \int_{0}^{1}\frac{x^{4}\left(1-x\right)^{4}}{1+x^{3}}dx =\frac{22}{7}-\pi \end{aligned} \]

Eq. 3
