SL Sinusoidal models

This section is all about sine waves and various transformations of them. These stand out from the other functions because they are cyclical in nature. As such, they are good for modelling occurrences that are cyclical too. For example weather cycles can often be modelled by sine waves - consider the average temperature cycle in a year where you live. Patterns in tides are also sinusoidal in nature.
