hello , I have question that has 3 parts- I'm confused and not sure where to start? would anyone be able to help? The question says: Letting d be the day of the year (from 1 to 365), you can figure the number of hours of sunlight, h(t) =2.4 sin (0.017d - 1.3777) + 12 Using this formula, a) when are we losing hours (minutes) of daylight the fastest? how many hours of daylight are there on that day? b)when are we losing hours (minutes) of daylight the slowest? c)when does the number of hours (minutes)lost slow down (i.e, the rate slows)
