Outside temperature over a day can be modeled as a sinusoidal function . Suppose you know the temperature is 55 degrees at midnight and the high and low temperature during the day are 70 and 40 degrees , respectively . Assuming t is the number of hours since midnight , find an equation for the temperature , D , in terms of t .D(t)=
