sine wave

The sine wave or sinusoid is a function that occurs often in mathematics, physics, signal processing, electrical engineering, and many other fields. Its most basic form is:which describes a wavelike function of time (t) with:peak deviation from center = A (aka amplitude)angular frequency  (radians per second)phase = θWhen the phase is non-zero, the entire waveform appears to be shifted in time by the amount θ/ω seconds. A negative value represents a delay, and a positive value represents a "head-start".
