For the data in Figure $4.30,$ sketch in the two approximating parabolas for Simpson's Rule. Compare the Simpson's Rule approximation to the Trapezoidal Rule approximation. Explain graphically why the Simpson's Rule approximation is smaller.
Added by David S.
Step 1
In this case, we have six data points, so we can divide the interval into three subintervals. The approximating parabolas for Simpson's Rule are quadratic functions that pass through three consecutive data points. We can use the first three data points to find the Show more…

Exact Simpson's Rule a. Use Simpson's Rule to approximate $\int_{0}^{4} x^{3} d x$ using two subintervals $(n=2) ;$ compare the approximation to the value of the integral. b. Use Simpson's Rule to approximate $\int_{0}^{4} x^{3} d x$ using four subintervals $(n=4) ;$ compare the approximation to the value of the integral. c. Use the error bound associated with Simpson's Rule given in Theorem 8.1 to explain why the approximations in parts (a) and (b) give the exact value of the integral. d. Use Theorem 8.1 to explain why a Simpson's Rule approximation using any (even) number of subintervals gives the exact value of $\int_{a}^{b} f(x) d x,$ where $f(x)$ is a polynomial of degree 3 or less.
