noun
angular frequency
Technical term used in physics and electrical engineering; the rate of change of phase of a sinusoidal waveform, measured in radians per second.
角周波数は、通常の周波数に2πを掛けたものです。
Angular frequency is the ordinary frequency multiplied by 2π.
周波数 is ordinary frequency (cycles per second, Hz), while 角周波数 is angular frequency (radians per second).
Compound of 角 (angle) + 周波数 (frequency), a calque of English 'angular frequency'.
