a) what is the amplitude of this function?
b) what is the period of this function?
c) determine a sine or cosine function that would model this data.
Transcribed Image Text:2. The percentage of the part of the moon facing earth that is illuminated can be modeled by a sinusoidal
function. 100% corresponds to a full moon, and 0% corresponds to a new moon. Create a sinusoidal function
based on the data presented, relating the percentage of the moon illuminated (I) as a function of the number of
days passed (T) since the start of data collection. Data was only collected on nights without cloud cover.
