Let the values of a function be tabulated at points equally spaced by , so , , ..., . Then Boole's rule approximating the integral of
is given by the Newton-Cotes-like
formula

This formula is frequently and mistakenly known as Bode's rule (Abramowitz and Stegun 1972, p. 886) as a result of a typo in an early reference, but is actually due to Boole (Boole and Moulton 1960).
