Webb10 apr. 2024 · The period for function y = A sin (B a – c) and y = A cos ( B a – c ) is equal to 2πB radians. The reciprocal of the period of a function is equal to its frequency. Frequency can be defined as the number of cycles completed per second (in a period of one second). If we denote the period of a function by P and let f be its frequency, then ... 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.
