Webb29 dec. 2024 · We may assume x 0 = − 1, x 1 = 0, x 2 = 1 and verify easily that Simpson's rule gives the correct integral values for the three parabolas y = a x 2 + b x + c having y = 1 at one of the three points and y = 0 at the other two points. This and the "linearity of everything" proves your claim.
