Assume that the time of the sunrise varies sinusoidally with the day
of the year. Let t be the time of day that the sun rises, and let D
be the number of the day of the year, starting with d=1 as January
1st. The longest day occurs on June 21st, and the sun rises at
5:34am. The shortest day occurs on December 21st, and the sun
rises at 7:24am.
Sketch a graph of this sinusoid.
