Question

Compare the formula for mutiple trapezoidal rule n=3 versus the addition of 3 single trapezoidal rule for the same problem. Compare the answer, will it be the same and why?

single trapezoidal rule :

Fа) + f(6) 1- (6 — а) Га) 2

Multiple trapezoidal rule :

  f(x)) f(x,) I (b-a)o) + (2 2n

EXAMPLE: f(x)=0.2+25x-200x2+675x3-900x4+400x5

a=0 b=0.8

Fа) + f(6) 1- (6 — а) Га) 2
f(x)) f(x,) I (b-a)o) + (2 2n

    1. Simpson's rule. Simpson's rule is a different formula for numerical integration of lºf (d.x which is based on approximating f(2) with a piecewise quadratic function. We will now derive Simpson's rule and relate it to Romberg integration: a. Suppose that (2) is a quadratic polynomial so that q(-h) = f(-h), q0) = f(0) and q(h) = f(h). Prove that 92 f(-h) + 4f(0) + f(h)). -h b. Suppose that the interval [a, b] is divided by a = 20,...

    MATLAB Create a function that provides a definite integration using Simpson's Rule Problem Summar This example demonstrates using instructor-provided and randomized inputs to assess a function problem. Custom numerical tolerances are used to assess the output. Simpson's Rule approximates the definite integral of a function f(x) on the interval a,a according to the following formula + f (ati) This approximation is in general more accurate than the trapezoidal rule, which itself is more accurate than the leftright-hand rules.
