WebThe sum is calculated by partitioningthe region into shapes (rectangles, trapezoids, parabolas, or cubics) that together form a region that is similar to the region being measured, then calculating the area for each of these shapes, and finally adding all of these small areas together. Web8 nov. 2024 · For a Riemann sum such as Ln = n − 1 ∑ i = 0f(xi)Δx, we can of course compute the sum even when f takes on negative values. We know that when f is positive on [a, b], a Riemann sum estimates the area bounded between f and the horizontal axis over the interval. Figure 3.2.7.
