Derivation of Simpson’s Rule Math 129 1. The form of Simpson’s Rule given in the book is SIMP(n) = 1 3 [2MID(n)+TRAP(n)] But TRAP(n) = [LEFT(n)+RIGHT(n)]/2 So SIMP(n) is really 1 3 [(LEFT(n)+RIGHT(n))/2+2MID(n)] or 1 3 (LEFT(n)/2+RIGHT(n)/2+2MID(n)) 2. So this suggests a refinement of the Riemann sum that approximates Z b a f(x)dx.

Simpson’s Rule. Simpson’s Rule takes advantage of the fact that most functions are smooth curves, not straight line segments. Simpson’s rule fits a parabola through the top three corners of each pair of strips and sums up the area under all of the parabolas.
