**Science / Tides and Currents / Harmonic Function:** In its simplest form, a quantity that varies as the cosine of an angle that increases uniformly with time. It may be expressed by the formula: y = A cos at in which y is a function of time (t), A is a constant coefficient, and a is the rate of change in the angle at.

**Function Noun Synonyms**: purpose, aim, role or r“le, raison d'ˆtre, responsibility, mission, charge, concern, business, province, duty, job, occupation, work, office, task, chore, assignment, commission, activity
