Answer:
The frequency of the sinusoidal graph = 2/π
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 :
One cycle of the sinusoidal function will complete at x = π/2
So, period = π/2
So, The frequency of the sinusoidal function = 2/π
