The graphs of the sunrise and sunset times in London (U.K.) throughout the year are shown below:
Can you explain the kinks in the curve?
Accurate data for various locations can be found at http://www.timeanddate.com/worldclock/sunrise.html
By making a simple adjustment, the sunrise and sunset times for London (U.K.) (without kinks !!!) can be modelled using the sine function.
Consider the sine function: $f(x)={a}\sin(bx+c)+d$
The project is to choose the values of the coefficients a, b, c and d to best model the annual cycle of sunrise (or sunset) times in London (U.K.).
