The trapezoidal rule is a numerical integration technique that can be used to calculate the area under a curve between two points. This method uses a series of straight lines connecting each point on the curve to its neighbours, with the sum of the areas of the trapezoids formed in this way being equal to the area under the curve. The formula ...The trapezoidal rule and Simpson’s rule are numerical approximation methods to be used to approximate the area under a curve. The area is divided into (n) equal pieces, called a subinterval or trapezoid. Each subinterval is approximated as a trapezoid considering the outer edge as straight line in the trapezoidal rule.Oct 25, 2020 · A combination of Trapezoidal and Simpson's rule (1/3 and 3/8) in evaluating a given set of data. If two points have unequal segments, the Trapezoidal rule would be applied. If 3 points have equal segments, Simpson's 1/3 rule would be applied. If 4 points have equal segments, Simpson's 3/8 rule would be applied. 6.
