Question

explain about trapezoid rule , simphson rule

Answer 1

In numerical analysis, Simpson's rule is a method for numerical integration, the numerical approximation of definite integrals. Specifically, it is the following approximation: ... Simpson's rule also corresponds to the three-point Newton-Cotes quadrature rule.The trapezoidal rule is one of a family of formulas for numerical integration called Newton–Cotes formulas, of which the midpoint rule is similar to the trapezoid rule.
