The average daily temperature in Phoenix, Arizona ranges from roughly 50 F on January 1st to 100 * F on July 1st. If t measures the time (in months) that has passed in a given year and T(t) is the average daily temperature in Phoenix, then we have T(0) = 50 and T(6) = 100. Assuming that T' is a sinusoidal function, find a formula for T(t). Enter your answer as a function T(t) = ... (Recall that a sinusoidal function has the form T(t) = A sin(Bt + C) + D where A, B, C and D are constants.)
