Definition of Periodicity of a Function
Let the domain of function f(x) be D. If there exists a non - zero constant T such that for any x ∈ D, x + T ∈ D and f(x + T) = f(x) holds, then f(x) is called…

Formula and explanation
Let the domain of function f(x) be D. If there exists a non - zero constant T such that for any x ∈ D, x + T ∈ D and f(x + T) = f(x) holds, then f(x) is called a periodic function, and T is called a period of this function. The minimal positive period (if it exists) is the smallest positive period.
