Can someone help me with this question? I'm bad at solving this problem. Outside temperature over a day can be modelled as a sinusoidal function. Suppose you know the high temperature for the day is 84 degrees and the low temperature of 56 degrees occurs at 4 AM. Assuming t is the number of hours since midnight, find an equation for the temperature, D, in terms of t. Please I want to know the solution and the answer. ASAP
