"WebHowever, Riemann sums will usually give more accurate approximations based on the number of rectangles and trapezoids; for example, an approximation using 4500 left rectangles will be better than simply using four rectangles to express the area under a curve. " - Lower approximation

Lower approximation

WebUpper and lower methods make the approximation using the largest and smallest endpoint values of each subinterval, respectively. The values of the sums converge as the subintervals halve from top-left to bottom-right. In mathematics, a Riemann sum is a certain kind of approximation of an integral by a finite sum. WebThe width of the entire area we are approximating is 10-1=9 10 −1 = 9 units. If we're using three equal subdivisions, then the width of each rectangle is 9\div 3=\blueD3 9÷3 = 3.
