# Boole's rule

In mathematics, **Boole's rule**, named after George Boole, is a method of numerical integration. It approximates an integral

by using the values of *ƒ* at five equally spaced points

It is expressed thus in Abramowitz and Stegun (1972, p. 886):

and the error term is

for some number *c* between *x*_{1} and *x*_{5}. (945 = 1 × 3 × 5 × 7 × 9.)

It is often known as Bode's rule, due to a typographical error that propagated from Abramowitz and Stegun (1972, p. 886).[1][2]
