In this project you will gather data for the sunrise and sunset times of the city where you live for one year. You will then use a sinusoidal function to describe this natural event.
Directions:
•Do a web for sunrise and sunset times for last year in a city near you.
•Starting with January 1 calculate the number of daylight hours every 30 days (you should have 13 items of data) convert the time from hours and minutes to the nearest tenth of an hour.
•Graph this set, the horizontal axis will represent the day of the year and the vertical axis will represent the number of daylight hours. Be sure to title graph and label the axis.
•Draw a regression curve, a curve that best represents your set of data.
•Answer following questions as well:
1.Locate lowest and highest points on your graph, and what is the amplitude?
2.There are 365 days a year, explain this value’s relationship in the graph.
3.What is the vertical shift on the graph?
4.What is the phase shift of the graph?
5.Write a sinusoidal function that models the number of daylight hours for the year in this city.
6.Using your equation, estimate the number of daylight hours in this city on the 220th day of the year. Based on your graph, does this answer seem reasonable? Explain any discrepancy that might occur between the two values.
