Part C: Parametric Equations for Curves

« Previous | Next »

Parametric equations define trajectories in space or in the plane. Very often we can think of the trajectory as that of a particle moving through space and the parameter as time. In this case, the parametric curve is written (x(t); y(t); z(t)), which gives the position of the particle at time t.

A moving particle also has a velocity and acceleration. These are vectors which vary in time. We will learn to compute them as derivatives of the position vector.
