product

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

\symbolname_{<em>lowerexpression</em>}^{<em>upperexpression</em>}

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

$\psi$
