#### phi (lower case greek letter)

$$\phi$$ gives $\phi$

#### Phi (upper case greek letter)

$$\Phi$$ gives $\Phi$

#### pi

$$x=\pi r^2$$ is $x=\pi r^2$

#### pi (lower case greek letter)

$$\pi$$ gives $\pi$

#### Pi (upper case greek letter)

$$\Pi$$ gives $\Pi$

#### plus

$$+$$ is $+$

#### plus minus

• 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 product symbol:

$$\bigprod_{i=k}^{n}$$   gives

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

and

$$\prod_{i=k}^{n}$$   gives

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

• Use font size commands for a nicer picture:

$$\LARGE\bigprod_{\tiny{i=k}}^{\tiny{n}}$$   gives

$\LARGE\bigprod_{\tiny{i=k}}^{\tiny{n}}$

and

$$\large\prod_{\small{i=k}}^{\small{n}}$$   gives

$\large\prod_{\small{i=k}}^{\small{n}}$

#### psi (lower case greek letter)

$$\psi$$ gives $\psi$
