4. Below are models for the number of hours of daylight in Seward, Alaska (60 degrees latitude) and New Orleans, Louisiana (30 degrees latitude).  Seward  D=12.2 – 6.4cos[π(t + 0.2)/6] New Orleans D=12.2– 1.9cos[π(t + 0.2)/6]  In these models, D represents the number of hours of daylight and t represents the month, with t=0 representing January 1.
