Answer:
Frequency = 1/period = [tex]\frac{1}{8\pi }[/tex]
Step-by-step explanation:
The frequency of the sinusoidal function = 1/period
Frequency is how many the function repeats itself per unit if time i.e: per "1"
For the given graph :
[tex]\frac{x}{4} =Bx[/tex] , Where: B = 2π/period
period = 2π/B , B = 1/4 = 0.25
∴ Period = 2π/0.25 = 8π
∴ Frequency = 1/period = [tex]\frac{1}{8\pi }[/tex]
