Answer 2

Answer:

Explanation:

In numerical analysis, a quadrature rule is an approximation of the definite integral of a function ... where g(x) is well-approximated by a low-degree polynomial, then alternative nodes x i ... will usually give more accurate quadrature rules. ... One may also want to integrate over semi-infinite (Gauss-​Laguerre quadrature) and ...
