Cyclic refers to something that occurs in a repeated or circular pattern. This concept can be seen in various fields, such as nature, where seasons like spring, summer, autumn, and winter repeat annually. In mathematics, cyclic groups are sets of elements that can be generated by repeatedly applying a specific operation. In addition to nature and mathematics, cyclic patterns are also present in everyday life. For example, the lunar cycle describes the phases of the moon as it orbits the Earth, repeating approximately every 29.5 days. Understanding cyclic phenomena helps us predict and analyze behaviors in different systems.
