Dutside temperature over a day can be modeled as a sinusoidal function. Suppose you know the temperature is 65 degrees at midnight and the high and low temperature during the day are SD and 5D degrees, respectively. Assuming t is the number of hours since midnight, find an equation for the temperature, D, in terms of t.
