Parametric Equations
- defines a group of quantities as functions of one or more independent variables called parameters
Parametric Equations - Examples
Unit Circle
The equations:
- 𝑥 = 𝑐𝑜𝑠 𝑡
- 𝑦 = 𝑠𝑖𝑛 𝑡
form a parametric representation of the unit circle, where 𝑡 is the parameter: a point (𝑥,𝑦) is on the unit circle if and only if there is a value of 𝑡 such that these two equations generate that point.
