PLS HELP!<br> What is the frequency of the sinusoidal graph?
docker41 [41]

the frequency of the sinusoidal graph is 2 in 2 π interval

Step-by-step explanation:

The frequency of the graphs refers to the number of the cycles, the graph completes in a given fixed interval.  

We already know the formula that  

         P= (1/ F)

Thus, F= (1/ P)

Where F= frequency and P= Period

Period is the horizontal length (x- axis component) of one complete cycle.

Thus, Observing the above graph

We find that the graph completes 1 cycle in π interval and 2 cycles in 2π interval

Thus, the frequency of the sinusoidal graph is 2 in 2 π interval
