Outside temperature over a day can be modelled using a sine or cosine function. Suppose you know the high temperature for the day is 62 degrees and the low temperature of 42 degrees occurs at 7 AM. Assuming \( t \) is the number of hours since midnight, find an equation for the temperature, \( D \), in terms of \( t \). \( D(t)= \)
