WEBNov 5, 2021 · Understanding Δx. You can see in the image that Δx = (b-a)/n. What does this mean? Our area is being taken on the interval [a, b], so b-a is just the length of our interval. For example, if we were finding the area on the interval [3, 8], b - a = 5. Similarly, n is the number of rectangles we have (in a perfect Riemann sum, n approaches infinity).
