SUMMARY
The average rate of change (AROC) of the function y = 2cos(x - π/3) + 1 over the interval π/2 < x < 5π/4 is calculated using the formula AROC = [f(x2) - f(x1)] / (x2 - x1). For this specific problem, x1 is π/2 and x2 is 5π/4. To find the exact AROC, evaluate the function at both endpoints: f(5π/4) and f(π/2), and substitute these values into the AROC formula.
