Sine waves of varying frequency, amplitude, and phase can construct any waveform

Evidence

Fourier theory states that any waveform can be built up by using an appropriate set of sine waves of different frequencies, amplitudes and phases. — David M. Howard, Jamie Angus, Acoustics and Psychoacoustics, 446
