sine wave

Sinusoidal waveform A waveform of periodic oscillations–eg, in alternating current in which the amplitude of each point in the wave is proportional to the sine of the time from a start point Cardiology An EKG finding described in severe hyperkalemia where the 'P' wave disappears and the QRS complex and 'T' wave merge in an oscillating pattern

sine wave

(sīn wāv)
A symmetric wave representing one complete cycle of a single-frequency oscillation; the displacement of mass over time described by using a function from trigonometry, the sine.
