-The seasonal variation in the length of daylight can be represented by a sine function. For example, the daily number of hours of daylight in a certain city in the U.S. can be given by $h = \frac { 41 } { 4 } + \frac { 5 } { 3 } \sin \frac { 2 \pi x } { 365 }$ , where $x$ is the number of days after March 21 ( disregarding leap year).
