Let be the length of the day of the year in Mumbai (formerly known as Bombay), India (measured in hours, from sunrise to sunset). We are given the following values of :
For example, means that the timefrom sunrise to sunset on February 16 is 11 hours and30 minutes. For locations close to the equator, the function is well approximated by a trigonometric functionof the form
(The period is 365 days, or 1 year.) Find this approximationfor Mumbai, and graph your solution. Accordingto this model, how long is the longest day of the year inMumbai?
