# Definition:Sequence of Partial Products

(Redirected from Definition:Partial Product)

## Definition

Let $p$ be the infinite product:

$\ds p = \prod_{n \mathop = 1}^\infty a_n$

The sequence $\sequence {p_N}$ defined as:

$\ds p_N: = \prod_{n \mathop = 1}^N a_n = a_1 \cdot a_2 \cdots a_N$

is the sequence of partial products of the infinite product $\ds p = \prod_{n \mathop = 1}^\infty a_n$.
