We will take here an example of modeling a pendulum attached to a spring, as shown in the following image. The pendulum swings to and fro. Furthermore, since the bob is attached to a spring, the bob also oscillates up and down:
We study the evolution of two variables over time:

- Angle (θ) between the spring and the center line, as shown in the preceding diagram.
Since there are two variables changing over time, the state ...
