Colorado Sunshine!!

Angelina Domenico Brittany Martinez

I saw the

sine!

& the sun rose over the horizon and set in the

west..• The objective of

this project is to show how sunrise and sunsets model a sine or cosine graph.

Why sunshine?

• We chose sunshine because there is certain time that the sun rises and sets,

• And if we can calculate how many hours of sunlight there is 3 days out of every month of the year

• We would have a cosine graph.

Soooo….

• We found a chart of all the times the sun rose and set.

• Then we found chose 3 days out of every month.– 1st

– 10th

– 30th (except February)

• Then found the amount of sunlight the day

1st of the month.

The first of the month you can see the sine

graph starting to form. If we were to repeat

the graph it would be a cosine graph

-5.5 cos 2 pi / 12 -5.5 cos 2 pi / 12 +9.5+9.5

10th of the month

Like the 1st of the month the 10th month makes a partial cosine graph. And if we continued it

would do the same thing over again

-5.5 cos 2 pi / 12 -5.5 cos 2 pi / 12 +9.5+9.5

It kind of looks like a cosine graph and if

we kept going through the next year it would look like a sine graph

-5 cos 2 pi / 12 + -5 cos 2 pi / 12 + 1010
