Simpson’s Rule is a useful formula to know, since it is more efficient than finding Midpoint Rule and Trapezoidal Rule estimates first, then combining the two. Also, the comprehensive formula is more accurate, since rounding errors introduced in the Midpoint and Trapezoidal Rules would get ...The trapezoidal rule for estimating definite integrals uses trapezoids rather than rectangles to approximate the area under a curve. To gain insight into the final form of the rule, consider the trapezoids shown in Figure 2. We assume that the length of each subinterval is given by [latex]\Delta x[/latex]. By dividing the interval [a, b] into many smaller intervals, and applying the trapezoidal rule to each, this allows us to find a better approximation the integral. Background.
