Modeling Periodic Behaviour
Periodic behaviour describes a function that repeats.
Some examples of periodic behaviour are:
1. The outside temperature as a function of time in years.
2. The amount of daylight on a daily basis.
3. The air pressure outside the eardrum as a pure tone is being heard.
4. The electric activity around the heart as viewed on an electrocardiogram (ECG).
5. The population of tent caterpillars; cycle of about 10 years.
6. The voltage on an AC (alternating current) electric circuit.
7. Financial stability in the market; recessions occur about once every 10 years; 1981, 1991, 2001, 2009
8. The motion of the Tacoma’s Bridge before it’s collapse in 1940.

Periodic events are characterized by the following descriptors:
• Cycle – one repetition in a repeating process.
• Period (T) – The change in the independent variable (typically time in seconds) corresponding to one cycle.
• Frequency (f) – the number of cycles that occur per every unit of the independent variable. If the independent variable is time measured in seconds then the frequency is measured in s-1 or Hz (Hertz).
• Amplitude – Half the range on a graph.
Ex; If the maximum temperature in Guelph is 28oC and the minimum temperature is –12oC over the seasons then the amplitude is
(28 – (-12))/2 = 20oC
Period and frequency are related by the equations:

Periodic Behaviour and their Graphs
Determine if each graph describes periodic behaviour. If the graph is periodic then label one cycle, determine the amplitude, period and frequency.
