The theory of Fourier series is concerned with the question of whether a given periodic function, such as the plot of a heartbeat or the signal of a radio pulsar, can be written as a sum of simple waves. A simple wave is described in mathematical terms as a function of the form csin (2πkx) or ccos (2πkx) for an integer k and a real or complex number c.
