$\Pi$

$a * b = c ^ b$

$2^{\frac{n-1}{3}}$

$\int_a^b f(x)\,dx.$

$$\int_a^b f(x)\,dx.$$

$$\begin{cases} \text{if true}\ foo \text{if false}\ bar \end{cases}$$

 $\rho {\rm{FOD}} = \sum\limits{\sigma ,i} {(\delta _1 - \delta _2 n_i^\sigma ) \phi _i^\sigma ({\bf{r}}) ^2}$

Tips:

• Use pipes (|) to delineate columns, and dashes to delineate the header row from the rest of the table.
• Spacing doesn’t matter to the markdown processor, any extra white space is removed, but it can really help with readability. The two markdown examples below both create this table.
 Use pipes ( ) to delineate columns, and dashes to delineate the header row from the rest of the table.
