Modelling with parametric equations

What can be modelled with parametric equations?

  • A common use for parametric equations is motion in two dimensions

    • x = f(t) – horizontal position, dependent on time

    • y = f(t) – vertical position, dependent on time

  • This is explored in vectors and projectiles

Worked Example

A model car, C, travels along a model track along the path of the curve shown in the diagram below and defined by the parametric equations

 x equals 2 cos t

y equals 3 sin 2 t 

where 0 less or equal than t less or equal than 2 pi

x and y are measured in metres, t is measured in minutes.
