The period is the duration of time of one cycle in a repeating event, so the period is the reciprocal of the frequency. For example, if a newborn baby's heart beats at a frequency of 120 times a minute, its periodâthe time interval between beatsâis half a second (that is, 60 seconds divided by 120 beats).
We may also calculate the period using the formula derived from the basic sine and cosine equations. The period for function y = A sin( B x - c ) and y = A cos( B x - c ) is $\frac{2 \pi}{B}$ radians. The reciprocal of period of a function is equal to its frequency. Frequency is defined as the number of cycles completed in one second. If the period of a function is denoted by P and f be its frequency, then -.
