(Modeling) Solve each problem. See Example 5.

Maximum Temperatures Because the values of the circular functions repeat every 2p, they are used to describe things that repeat periodically. For example, the maximum afternoon temperature in a given city might be modeled by

where t represents the maximum afternoon temperature in month x, with x = 0 representing January, x = 1 representing February, and so on. Find the maximum afternoon temperature for each of the following months.

(a) January

(b) April

(c) May

(d) June

(e) August

(f) October
