It is very accurate for in-tegrals over periodic intervals, but is usually quite inaccurate in nonperiodic cases. Com-monly used improvements, such as Simpson’s rule and the Newton{Cotes formulas, are

WebTrapezoidal rule: f (x)dx Itrapezoidal(f;x0,x1 ) = -f'' (x), x [x0,x1] The truncation error of the trapezoidal rule is proportional to h3, i.e. it has the order of O (h3). The error is also proportional to the second derivative of the function f (x) at an interior point x of the integration interval. WebThe thick blue curve is the function to be integrated, the upper diagonal line is the top of the trapezoid from the trapezoidal rule, and the bottom diagonal line (which is tangent to the blue curve) is the top of the trapezoid with the same …
WebThe truncation error of the composite trapezoidal rule has the order of O (h2), where the coefficient is proportional to the length of the interval, i.e. to T, and to the second derivative of I'' (t), where t is in the intermediate interval: 0 < t < T. Midpoint rule can be used in combination with the trapezoidal or Simpson's rules, e.g., the two …
