#### rho (lower case greek letter)

$$\rho$$ gives $\rho$

#### sigma (lower case greek letter)

$$\sigma$$ gives $\sigma$

#### Sigma (upper case greek letter)

$$\Sigma$$ gives $\Sigma$

#### sum (summation)

• General syntax for symbols with a kind of lower and upper limits:

\symbolname_{lowerexpression}^{upperexpression}

• In general, there are two ways how these lower and upper expressions can be placed: centered below and above the symbol or in a subscript / superscript manner. In the first case the symbol name is preceded by the word "big", in the second there is no prefix.
• Syntax for summation symbol:

$$\bigsum_{i=k}^{n}$$   gives

$\bigsum_{i=k}^{n}$

and

$$\sum_{i=k}^{n}$$   gives

$\sum_{i=k}^{n}$

• Use font size commands for a nicer picture:

$$\LARGE\bigsum_{\small{i=1}}^{\small{n}}$$   gives

$\LARGE\bigsum_{\small{i=1}}^{\small{n}}$

and

$$\large\sum_{\small{i=1}}^{\small{n}}$$   gives

$\large\sum_{\small{i=1}}^{\small{n}}$

#### tau (lower case greek letter)

$$\tau$$ gives $\tau$

#### theta (lower case greek letter)

$$\theta$$ gives $\theta$

#### Theta (upper case greek letter)

$$\Theta$$ gives $\Theta$

#### times

$$a\times~b$$ gives $a\times~b$
