Use the Trapezoidal rule to estimate the area of the field. The area of the same field was re-estimated by applying the Trapezoidal rule again. This time, a different section width (4 m) and a different set of section heights were used, as shown below. The area was found to be 145∙6 m2.

With the trapezoid rule, instead of approximating area by using rectangles (as you do with the left, right, and midpoint rectangle methods), you approximate area with — can you guess? — trapezoids. Because of the way trapezoids hug the curve, they give you a much better area estimate than either left or right rectangles. And […]

Trapezoidal Rule for Integration (Definition, Formula, and ...

Trapezoidal Rule. A greater mathematical challenge can be introduced by considering a scenario where the existing ground slopes across the width of the cross section, say, at a slope of 1:10. The side slope of the embankment can also be varied from that-4

I. Multistep Methods 283 The Adams family of methods arises when we approximate the integralontherightof𝑦(𝑡𝑛+1)−𝑦(𝑡𝑛)= ∫𝑡 𝑛+1 𝑡𝑛 𝑦′(𝑠)𝑑𝑠with ∫ 𝑡 𝑛+1 𝑡𝑛 𝑃𝐴⋅ 𝑚(𝑠)𝑑𝑠. where 𝑃𝐴⋅ interpolates 𝑦′(𝑠) at a prescribed set of time-steps, and then discretize. For the explicit Adams-Bashforth Methods, AB𝑚,

(a) Use two applications of the trapezoidal rule to calculate the approximate area of the garden. (b) Should the answer to part (a) be more than, equal to or less than the actual area of the garden? Referring to the diagram above, briefly explain your answer.

· Although the trapezoidal rule is a simple way to calculate the area under a curve, you should never forget that it is an approximate method. The more points you have, the better the results you get. Furthermore, be careful not to confuse the curve area with the value of the definite integral.
