Suppose the rate of gasoline consumption in the United States can be modeled by a sinusoidal function of the form ( 11.21 − cos ( π t 6 ) ) × 10 9 gal/mo . What is the average monthly consumption, and for which values of t is the rate at time t equal to the average rate? What is the number of gallons of gasoline consumed in the United States in a year? Write an integral that expresses the average monthly U.S. gas consumption during the part of the year between the beginning of April ( t = 3) and the end of September ( t = 9).

Write an integral that expresses the average monthly U.S. gas consumption during the part of the year between the beginning of April (t = 3) and the end of September (t = 9).
With differentiation, one of the major concepts of calculus. Integration involves the calculation of an integral, which is useful to find many quantities such as areas, volumes, and displacement.
