Three harmonics of a wave of fundamental frequency

Reference no: EM13674694

An acoustic signal is composed of the first three harmonics of a wave of fundamental frequency 470 Hz. If these harmonics are explained, in order, by cosine waves with amplitudes of 0.710, 0.170, and 0.790, what is the total amplitude of the signal at time 0.414 seconds? Suppose the waves have phase angles n = 0.
