Sovle problem and illustrate in detail STEP BY STEP how you inputed into the calculator. Average daily temperature T of city in United States is approximated by
\(T=55-23cos(2\pi/365)(t-30)\)
where t is in days, 1 is less than or equal to t less than or equal to 365, and t =1 corresponds to January 1. For what range of values of t is average daily temperature above 70 degrees F?
