This is is a test:  $a^2 + b^2 = c^2$           \\
This is another test: \(1+2+\dots+n=\frac{n(n+1)}{2}\)  

To display math on its own line, use double dollar signs:\\
 => ''$$ \frac{d}{dx}\left( \int_{0}^{x} f(u)\,du\right)=f(x) $$'' \\ 
gives:
$$ \frac{d}{dx}\left( \int_{0}^{x} f(u)\,du\right)=f(x) $$

or escaped square brackets: \\
=>  ''\[ \sin A \cos B = \frac{1}{2}\left[ \sin(A-B)+\sin(A+B) \right] \]''\\
gives:
\[ \sin A \cos B = \frac{1}{2}\left[ \sin(A-B)+\sin(A+B) \right] \]


Numbered equations:

(tab) If $\hat T_p$ is the complex fourier tranform, the bispectrum (triple correlation) is: 
\begin{equation}
\hat T_{p,q}^{(3)}=\hat T_p.\hat T_q. \hat T_{-p-q}
\end{equation}
