Because the values of circular functions repeat every 2, they are used to describe things that repeat periodically. For example, the maximum afternoon temperature in a given city might be modeled by the formula below. In the formula, t represents the maximum afternoon temperature in month x, with x=0 representing January, x = 1 representing February, and so on. t=40-20 cos 6 The maximum afternoon temperature in March is 30. (Round to the nearest integer as needed.) In May, the maximum afternoon temperature is . (Round to the nearest integer as needed.)
