The graph of a typical function y = ƒ(x) over [a, b]. Partition [a, b] into n subintervals a < x 1 < x 2 <…x n < b. Select a number in each subinterval c k. Form the product f(c k ) x k. Then take the sum of these products. 5.2

8
The curve of with rectangles from finer partitions of [a, b]. Finer partitions create more rectangles with shorter bases.

9
The definite integral of f(x) on [a, b] If f(x) is non-negative, then the definite integral represents the area of the region under the curve and above the x-axis between the vertical lines x =a and x = b

Indefinite Integrals and Net Change The integral of a rate of change is the net change. If the function is non-negative, net area = area. If the function has negative values, the integral must be split into separate parts determined by f(x) = 0. Integrate one part where f(x) > 0 and the other where f(x) < 0. but

17
Indefinite Integrals and Net Change The integral of a rate of change is the net change. If the function is non-negative, displacement = distance. If the function has negative values, the integral Must be split into separate parts determined by v = 0. Integrate one part where v>0 and the other where v<0.
