The value of the function at 3π/2 is 1.
The value of the function at 2π is 3.
If f(x) represents this function, the rate of change from x = 3π/2 to x = 2π can be expressed as:

Using the values in this formula, we get:
This means, the rate of change of the function from x = 3π/2 to x = 2π is 4/π. So option A gives the correct answer
