Inverse Trigonometric Functions · Exercise 122

Find the amplitude, period, phase shift, and midline.

The outside temperature over the course of a day can be modeled as a sinusoidal function. Suppose you know the temperature is 68°F at midnight and the high and low temperatures during the day are 80°F and 56°F, respectively. Assuming is the number of hours since midnight, find a function for the temperature, in terms of
