About our Simpson's 1/3 Rule Calculator

Simpson's Rule is a numerical integration technique that approximates definite integrals by fitting quadratic polynomials (parabolas) over pairs of sub-intervals. It provides significantly higher accuracy than the Trapezoidal Rule.

Error Formula

The global truncation error of Simpson's 1/3 Rule is proportional to O(h^4), making it exact for polynomials up to degree 3.
