In the last section, Trapezoidal Rule, we used straight lines to model a curve and learned that it was an improvement over using rectangles for finding areas under curves because we had much less "missing" from each segment.

Calculus: Trapezoid Rule Quiz I. Area of Trapezoid Find the area of each trapezoid SOLUTIONS Area = 42 Area = 2 (base 1 + base 2 )(height) Area = Il. Trapezoid Sums 1) Using the trapezoid rule, where the number of sub-intervals n = 4, approximate the area underfx) in the interval [O, 4]. The interval span is 4... So, each of the 4 In the last section, Trapezoidal Rule, we used straight lines to model a curve and learned that it was an improvement over using rectangles for finding areas under curves because we had much less "missing" from each segment.

The Trapezoidal Rule is a numerical approach to finding definite integrals where no other method is possible. The Trapezoidal Rule is based on Newton-Cotes Formula which is as follows: where The results can be improved by partitioning the integration interval and using the trapezoidal rule to all subintervals and summing up the results. The Trapezoidal Rule is based on Newton-Cotes Formula which is as follows: where The results can be improved by partitioning the integration interval and using the trapezoidal rule to all subintervals and summing up the results.

The Trapezoid Rule: For the function in the above figure with three trapezoids, here’s the math: Even though the formal definition of the definite integral is based on the sum of an infinite number of rectangles, you might want to think of integration as the limit of the trapezoid rule at infinity. A graph is a trapezoid graph if there exists a set of trapezoids corresponding to the vertices of the graph such that two vertices are joined by an edge if and only if the corresponding trapezoids intersect.
