SUMMARY
Gaussian Integration in one dimension with n points integrates exactly with a polynomial of order 2n-1 due to its ability to approximate the integrand using a polynomial function that passes through those n points. The approximation is accurate when the integrand is a polynomial of degree n-1, resulting in an exact integration outcome. This method leverages the properties of polynomial interpolation to achieve precise results for specific classes of functions.
