Identify Maximum Sunlight Hours: To find the maximum number of sunlight hours, look at the constant and the amplitude in the function D(t)=12−6.6cos(3652πt). The max sunlight hours will be when the cosine function is at its minimum, which is −1.
Calculate Maximum Sunlight Hours: Calculate the maximum number of sunlight hours: Dmax=12−6.6×(−1)=12+6.6=18.6 hours.
Determine Period of Function: The period of the function D(t) is the time it takes for the function to repeat. Since the cosine function has a period of 2π, and there's a coefficient of (2π/365) in front of t, the period of D(t) is 365 days.
Find Amplitude of Function: The amplitude of the function D(t) is the absolute value of the coefficient in front of the cosine function, which is 6.6 hours of sunlight in a day.
