WebFirst, a Riemann Sum gives you a "signed area" -- that is, an area, but where some (or all) of the area can be considered negative. Really, it adds up the distance above the axis that the curve is. So if it's below the axis, that's a negative distance above. That's where these negatives are coming from. When you're taking the distance between ...

WebThen the area of this rectangle is f(xi − 1)Δx. Adding the areas of all these rectangles, we get an approximate value for A ( Figure 5.3 ).
