I'm supposed to be graphing the time of sunrise, every week in New York of the 2003 year and the requirement is for the graph to be in sinusoid form. I'm thinking that it'd be best to graph it in negative sine form because the time of sunrise decreases from the 1st week to the 24th week, then increases from the 25th week to the 52nd week. Also, if you think you know the line of best fit, that'd be welcome so that I can compare mine to yours.
