PERIODIC FUNCTION Meaning and
Definition
-
A periodic function is a mathematical function that repeats its values at regular intervals called periods. It is a fundamental concept in mathematics and has applications in various fields, such as physics, engineering, and signal processing.
Formally, a periodic function f(x) is defined as a function for which there exists a positive constant P (period) such that f(x + P) = f(x) for all x in the domain of the function. In other words, if we shift the value of x by the period P, the function repeats its values. The period is the smallest positive value of P that satisfies this property.
A periodic function can be represented graphically as a pattern that repeats itself indefinitely. Common examples of periodic functions include sine, cosine, and tangent functions. These functions have a period of 2π radians or 360 degrees and repeat their values every 2π units.
The concept of periodicity is essential in understanding the behavior and properties of various phenomena. It allows us to study and analyze repetitive patterns, oscillations, and cyclical behaviors, both in mathematics and the physical world. Periodic functions have many useful properties, including symmetry, harmonics, and Fourier series representation.
Overall, a periodic function is a mathematical function that exhibits a repetitive pattern and repeats its values at regular intervals called periods. It provides a fundamental framework for understanding and analyzing various phenomena, making it a vital concept in mathematics and other scientific disciplines.

Etymology of PERIODIC FUNCTION
The word "periodic" originated from the Latin word "periodicus", deriving from the Greek word "periodikos" (περιοδικός), which means "occurring at regular intervals". "Periodikos" is formed from the Greek words "peri" (περί), meaning "around" or "about", and "hodos" (ὁδός), meaning "way" or "path".
The term "function" comes from the Latin word "functio", which means "performance" or "execution". It originated from the Latin word "fungi", meaning "to perform" or "to discharge".
Therefore, the term "periodic function" refers to a mathematical function that repeats its values at regular intervals as it follows a particular path or course.
