Figure 4 – Midpoint rule for integration. On the left side of the figure, we show how to manually calculate the definite integral ∫f(x)dx from x = 1 to x = 2 by using the midpoint rule with 10 subintervals to obtain the value .149889. Here, delta = (2-1)/10 = .1. Using the INTEGRAL function, we obtain the same value as shown in cell L9.
Use this online midpoint rule calculator for computing the table of integrals of the given function over the interval (a, b) using the midpoint formula. This rule uses the midpoint of every interval as the point at which it evaluates the given function for the Riemann sum.
Free Midpoint Rule calculator - approximate the area of a curve using Midpoint Rule (Riemann) step-by-step
The Midpoint Rule is a numerical method used to approximate the value of a definite integral. It provides a way to estimate the area under a curve, which is particularly useful when the integral cannot be calculated directly.
