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.

By dividing the interval [a, b] into many smaller intervals, and applying the trapezoidal rule to each, this allows us to find a better approximation the integral.
