What is the frequency of the sinusoidal graph?

A sinusoidal function with the x axis beginning at negative pi over 2 and increasing in increments of pi over two until reaching five pi over two. The function begins at negative pi over 2 comma 1 and then decreases to a minimum point then passes through zero comma zero and increases to a maximum value. The graph then decreases to a minimum value of pi over two comma negative one. The graph then increases to a maximum value and then decreases through pi comma zero to a minimum value. The graph then increases to a maximum value of three pi over two comma one. The graph then decreases to a minimum value and then passes 2 pi comma 0 and increases to a maximum value and then decreases to a minimum value of 5 pi over 2 comma negative one.

The frequency  is    1 / period

 

We have 3 periods in 2pi.....so.....the period is  2pi / 3

 

So....the frequency is

 

1 / [ 2pi /3 ]  =

 

3 / [ 2pi ]

 

 

cool cool cool
