The sine wave or sinusoid is a function that occurs often in mathematics, physics, signal processing, audition, electrical engineering, and many other fields. Its most basic form is: » y (t) = A cdot sin(omega t + heta) which describes a wavelike function of time (t) with: peak deviation from center = A (aka amplitude) angular frequency omega, (radians per second) phase = θ When the phase is non-zero, the entire waveform appears to be shifted in time by the amount θ/ω sec… (More on Sinusoid)
