Numerical Analysis: Trapezoidal and Simpson's Rule
www.math.utep.eduNumerical Analysis: Trapezoidal and Simpson’s Rule Natasha S. Sharma, PhD General Trapezoidal Rule T n(f) 1 We saw the trapezoidal rule T 1(f) for 2 points a and b. 2 The rule T 2(f) for 3 points involves three equidistant points: a, a+b 2 and b. 3 We observed the improvement in the accuracy of T 2(f) over T 1(f) so inspired by this, we would like to apply this rule to n + 1 …

homepage.math.uiowa.eduTHE TRAPEZOIDAL METHOD The backward Euler method is stable, but still is lacking in accuracy. A similar but more accurate numerical method is the trapezoidal method: y n+1 = y n + h 2 [f (x n;y n) + f (x n+1;y n+1)]; n = 0;1;::: (6) It is derived by applying the simple trapezoidal numerical integration rule to the equation Y(x n+1) = Y(x n) + Z ...
