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. Here the trapezoidal rule approximates the function by a suitable chosen (not necessarily horizontal) line segment. The function values at two points in the interval are used in the approximation. While Simpson's rule uses a suitably chosen parabolic shape (see Section 4.6 of the text) and uses the function values at three points. To Explain: Trapezoidal Rule or Simpsons Rule which one gives the better approximation. Explanation: Trapezoidal Rule mostly defines the average of the left and right hand of the Riemann Sums while Simpsons Rule defines the weighted average that gives the accurate approximation because in Simpsons Rule quadratic approximation is used instead of …called the Trapezoidal rule and the Simpson’s rule which can be derived by integrating the Lagrange interpolating polynomials of degree 1 and 2 respectively.

Note: the previous 4 methods are also called Riemann Sums after the mathematician Bernhard Riemann. Simpson's Rule. An improvement on the Trapezoidal Rule is Simpson's Rule. It is based on using parabolas at the top instead of straight lines. The parabolas often get quite close to the real curve:In the task of estimation of full area of narrow peak-like functions, Simpson's rules are much less efficient than trapezoidal rule. Namely, composite Simpson's 1/3 rule requires 1.8 times more points to achieve the same accuracy as trapezoidal rule. Composite Simpson's 3/8 rule is even less accurate.
