In a left Riemann sum, we approximate the area using rectangles (usually of equal width), where the height of each rectangle is equal to the value of the function at the left endpoint of its base. y x.\(\displaystyle R_{100}=0.33835,L_{100}=0.32835.\) The plot shows that the left Riemann sum is an underestimate because the function is increasing. Similarly, the right Riemann sum is an overestimate. The area lies between the left and right Riemann sums. Ten rectangles are shown for visual clarity. This behavior persists for more rectangles. We’ve already calculated the height at x = 1 to be 24, so the first rectangle for the right Riemann sum is then 24 units tall. The second rectangle’s right corner lies on x = 2, and again, we already know the height there. Since f ( 2) = 42, the second rectangle is 42 units tall. The third rectangle ends at , and will have a height of 48.The area under a curve is commonly approximated using rectangles (e.g. left, right, and midpoint Riemann sums), but it can also be approximated by trapezoids.
