Definition:Parametric Equation/Parameter

Definition
Let $n \in \Z_{>0}$ be a positive integer.

Let:
 * $\set {\phi_k: 1 \le k \le n}$

be a set of parametric equations such that:


 * $x_k = \map {\phi_k} t$

for some independent variable $t$.

$t$ is referred to as the (independent) parameter of $\set {\phi_k: 1 \le k \le n}$.
