Abstract
We can approximate the area under a curve by partitioning the region into rectangular sections and calculating the area of the rectangles (Figure 20.1(a)). The greater the number of rectangles, the more accurate the approximation of the area (Figure 20.1(b)). By inspection of the curve, we see that the area under it must be about (4×2) − 2 = 6.
