Problem 31

A curling iron is plugged into an outlet at time t = 0. Its temperature T in degrees Fahrenheit, assumed to be a continuous function that is strictly increasing and concave down on 0 t 120, is given at various times (in seconds) in the table. a. Approximate 1 120L 120 0 T1t2 dt in three ways: using a left Riemann sum, a right Riemann sum, and the Trapezoid Rule. Interpret the value of 1 120L 120 0 T1t2 dt in the context of this problem. b. Which of the estimates made in part (a) overestimates the value of 1 120L 120 0 T1t2 dt? Underestimates? Justify your answers with a simple sketch of the sums you computed. c. Evaluate and interpret L 120 0 T_1t2 dt in the context of this problem.
