9 lut 2018 · The composite trapezoidal rule is a method for approximating a definite integral by evaluating the integrand at n n points. Let [a,b] [ a, b] be the interval of integration with a partition a = x0 <x1 < … <xn = b a = x 0 < x 1 < … < x n = b. Then the formal rule is given by.
The trapezoidal rule gives us a technique to approximate the integral on a given interval [ a, b ], but we cannot reduce the error because the error depends on the width of the interval over which we are integrating.
