Error Bound Calculator (Simpsons Rule)

To calculate the error bound using Simpson’s Rule, evaluate the maximum value of the fourth derivative of the function and apply it to the error formula for precise estimation.

The Error Bound Calculator (Simpson’s Rule) helps estimate the error in numerical integration using Simpson’s Rule. It is an essential tool in numerical methods, providing accuracy assurance when approximating definite integrals.

By evaluating the maximum value of the fourth derivative of the integrand and other parameters, this calculator gives a reliable error bound. This tool is particularly useful for students, engineers, and mathematicians who deal with numerical approximations regularly.

Formula

$n > \frac{[(b – a)^5] ∗ M}{180 ∗ ε^{1/4}}$

Variable	Description
n	Minimum number of subintervals
a, b	Lower and upper limits of the integral
M	Maximum value of the fourth derivative of $f(x)$
ε	Tolerable error

Solved Calculations

Example 1:
Find the minimum number of subintervals ( $n$ ) for integrating $f(x)$ on $[1, 3]$ with $M = 50$ and an error tolerance of 0.001.

Step	Calculation	Result
Limits ( $a, b$ )	$1, 3$
Maximum Derivative ( $M$ )	$50$
Tolerance ( $ε$ )	$0.001$
Apply Formula	$n > \frac{[(3 – 1)^5] ∗ 50}{180 ∗ 0.001^{1/4}}$	$n > 4.45$

Example 2:
Calculate $n$ for $[0, 2]$ , $M = 30$ , and error tolerance $ε = 0.005$ .

Step	Calculation	Result
Limits ( $a, b$ )	$0, 2$
Maximum Derivative ( $M$ )	$30$
Tolerance ( $ε$ )	$0.005$
Apply Formula	$n > \frac{[(2 – 0)^5] ∗ 30}{180 ∗ 0.005^{1/4}}$	$n > 3.73$
