The period T and the frequency f are reciprocals of each other, that is, $T=1/f$ and $f=1/T$. As we have seen, hertz is a measure of cyclic frequency, that is, a measure of the number of cycles per second. However, there is yet another type of frequency: the angular frequency $\omega$, which is measured in radians per second. Angular frequency is related to cyclic frequency f by the fundamental relation
