Half-period ratio

The half-period ratio, often referred to in the context of periodic functions, is a mathematical concept that describes the relationship between the periods of a function and its symmetry properties. Specifically, for a periodic function, the half-period ratio relates the half-period to the full period of the function. More formally, if \( T \) is the full period of a periodic function, then the half-period, denoted as \( T/2 \), is simply half of that period.
