Unformatted text preview: a, b ] into n subintervals: [ x , x 1 ] , [ x 1 , x 2 ] , , [ x n1 , x n ] where x = a, x n = b, x k +1 = x k + x for 0 k n1 Compute R n and L n : R n = f ( x 1 ) x + f ( x 2 ) x + + f ( x n ) x L n = f ( x ) x + f ( x 1 ) x + + f ( x n1 ) x Denition. The area of the region S bounded by the graph of a nonnegative continuous function f , the xaxis and the vertical lines x = a and x = b is A = lim n R n = lim n L n . The velocity graph of a car accelerating from rest to a speed of 120 km/h over a period of 30 seconds is shown. Estimate the distance traveled during this period.6 v (km/h) 80 40 10 20 30 t (seconds)...
