Midpoint and trapezoidal sums in summation notation

Numerical integration methods can generally be described as combining evaluations of the integrand to get an approximation to the integral. The integrand is evaluated at a finite set of points called integration points and a weighted sum of these values is used to approximate the integral.

Midpoint formula for integration

WebFirst, recall that the area of a trapezoid with a height of h and bases of length b1 b 1 and b2 b 2 is given by Area= 1 2h(b1 +b2) Area = 1 2 h ( b 1 + b 2). We see that the first trapezoid has a height Δx Δ x and parallel bases of length f (x0) f ( x 0) and f (x1) f ( x 1). Thus, the area of the first trapezoid in Figure 2 is.
