In numerical analysis, Simpson's 3/8 rule (method) is a technique for approximating definite integral of a continuous function. This method is based on Newton's Cote Quadrature Formula and Simpson 3/8 rule is obtained when we put value of n = 3 in this formula.
Computer Algorithm for Mixed Simpson 1/3 and 3/8 Rule for Integration. Based on the earlier discussion on (single and composite) Simpson 1/3 and 3/8 rules, the following “pseudo” step-by-step mixed Simpson rules for estimating \[I = \int_{a}^{b}{f(x){dx}}\] can be given as. Step 1. User inputs information, such as \[f(x) = \text{integrand}\]

It can be proved that single segment application of Simpson’s 1=3 rule has a truncation error of Et = ¡ 1 90 h5f(4)(») where » is between a and b. Simpson’s 1=3 rule yields exact results for third order polynomials even though it is derived from parabola. Example: Use Simpson’s 1=3 rule to integrate f(x) = 0:2+25x+3x2 +8x3 from a = 0 ...
3 gru 2019 · In this tutorial, we will be discussing a program to implement SImpson’s ⅜ rule. Simpson’s ⅜ rule is used for doing numerical integrations. The most common use case of this method is in performing numerical approximations of definite integrals.

Example 1. Let f[x] be. (a) Numerically approximate the integral by using Simpson's 3/8 rule with m = 1, 2, 4. (b) Find the analytic value of the integral (i.e. find the "true value"). (c) Find the error for the Simpson' 3/8 rule approximations. Solution 1 (a). We will use simulated hand computations for the solution. (1. Solution 1 (b).
