Question


b. Since it is early in the morning, the temperature has been decreasing for some length of time rather than remaining constant. Suppose that a more accurate cooling law is given by the differential equation


c. In the trigonometric section, we found that the daily temperature is often well approximated by a trigonometric function. Suppose that the environmental temperature is approximated by the function:

Temperature at 7 AM = .

The minimum temperature has what value and occurs what time during the night.

Minimum temperature = .
Clock Time of Min Temp = : AM,
where the minutes are a decimal value with at least 4 significant figures.


Explanation / Answer

b. Since it is early in the morning, the temperature has been decreasing for som
