Integration by Simpson's 1/3 rule can be represented as a weighted average with 2/3 of the value coming from integration by the trapezoidal rule with step h and 1/3 of the value coming from integration by the rectangle rule with step 2h. The accuracy is governed by the second (2h step) term. WebbThis program is coded using Python and uses two adaptive variable step-size integration methods (adaptive trapezoidal rule and adaptive Simpson's rule) to calculate the numerical integral value of a function. jobst maternity pantyhose
