The period and frequency of a cosine function
WebbPeriod and frequency are reciprocals of each other in Physics, i.e. P = 1/f and f = 1/P. When discussing the graphs of trig functions, the Period is the length of a cycle. The term "frequency" is not formally defined. For example, sin (x) has a period of 2pi, since sin (x) = sin (x + 2pi) and it is the smallest angle for which that is true. WebbFor periodic motion, frequency is the number of oscillations per unit time. The relationship between frequency and period is. f = 1 T. 15.1. The SI unit for frequency is the hertz (Hz) and is defined as one cycle per second: 1 Hz = 1 cycle s or 1 Hz = 1 s = 1 s −1. A cycle is one complete oscillation.
