True or False: Gaussian quadrature is less effective for smooth functions.
- True
- False
Show hintHide hint
Recall the characteristics that make Gaussian quadrature useful.
Question 5.
Consider a smooth function f(x) = sin(x) on the interval [0, π]. Compare the approximate integral using Gaussian quadrature (2-point) with the true integral. How does the accuracy compare?
Show hintHide hint
Evaluate using specified nodes and compare to the exact integral value.
Question 6.
Challenge yourself to derive a situation in which a rapidly oscillating function might mislead Gaussian quadrature measures. Describe the outcome.
