$\frac{\Delta y}{\Delta x} = \frac{f(x+h)- f(x)}{h}$

$\Delta y$

$y = \int f(x) dx$

Some further tests:

$\sum \vec{F}_{T} = \frac{\sum \vec{\tau}_{T}}{|\left(\vec{r}_{A} - \vec{r}_{R} \right)|}$

Testing relativity formulas for the thread which name we do not mention...

$t = \frac{{t}' + \frac{v{x}'}{c^{2}}}{\sqrt{1 - \frac{v^{2}}{c^{2}}}}$

$t = \frac{{0} + {0.8} . {0.6} }{\sqrt{1 - {0.8 ^{2}}}}$

Testing more stuff.

$f\left(x\right)=\begin{cases} 1, & x\in\mathbb{Q}\\ -1, & x\in\mathbb{R}-\mathbb{Q} \end{cases}$

Testing more stuff.

$\textrm{int}C\neq\textrm{Ø}\Rightarrow\textrm{if }x\in C\Rightarrow\in B_{\epsilon}\left(x\right)\subseteq C\Rightarrow\mu\left(C\right)\geq\mu\left(B_{\epsilon}\left(x\right)\right)>0$

Rather:

$\textrm{int}C\neq\textrm{Ø}\Rightarrow\textrm{if }x\in C\Rightarrow B_{\epsilon}\left(x\right)\subseteq C\Rightarrow\mu\left(C\right)\geq\mu\left(B_{\epsilon}\left(x\right)\right)>0$

Total energy:

$E=\frac{mc^{2}}{\sqrt{1-v^{2}/c^{2}}}$

Rest energy:

$E_{0}=mc^{2}$

Kinetic energy:

$\textrm{K.E.}=\frac{mc^{2}}{\sqrt{1-v^{2}/c^{2}}}-mc^{2}$

$\int (f(x)+ dy/2)dx= \int f(x)dx+ \frac{1}{2}\int dydx$

$\frac{1}{2}\int dydx$

Inline: $$dy\left( x \right) = y'\left( x \right) dx$$.

(f(x)+dy/2)dx=f(x)dx+12dydx

12dydx

Inline: dy(x)=y(x)dx .

@joigus, how did you center your equations?

I cannot get \begin{center} command to work.
