Periodic Data Examples

Periodic Data: a data set that repeats the same pattern over time

Handout: Periodic Data

Example 1: The percent of the face of the moon we see each night

Example 2: The Bay of Fundy tides

Example 2: Volume displacement in an engine cylinder (credit Stephen Jull)

Example 3: Height above the ground on the London Eye Ferris Wheel

We can use trigonometric functions to describe periodic behaviour. If the repetition is a little more complex, a fourier series might be used:

Example 4: Fourier Series (what are they), Fourier Series – beyond this course but you can see Sal Khan work some out.
