function that repeats its values in regular intervals or periods
AI overview
A periodic function is a mathematical function that repeats the same pattern of values over and over again at regular intervals. This concept matters because many natural phenomena—like the motion of pendulums, ocean tides, and sound waves—follow repeating patterns, making periodic functions essential tools for understanding and predicting these everyday occurrences.
