WebThe x-axis shows the measure of an angle. We know y=cos(x) completes a full cycle or period for every change of 2π radians along the x-axis, and as a consequence cos(2π) = … WebPeriod 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. google weather kennedy meadowsWebYou may also say that it has a frequency of 1 Hz.
