in trpezoidal rule for numerical integration how you can find error
The number of sub-intervals required to use the Trapezoidal rule in numerical integration depends on the desired accuracy and the nature of the function being integrated. Generally, more sub-intervals lead to a better approximation of the integral. To determine an appropriate number, one can estimate the error and adjust the sub-intervals accordingly, often using criteria such as the error bound formula for the Trapezoidal rule. A common approach is to start with a small number of sub-intervals and increase them until the desired accuracy is achieved.
It's because the diagonal line on each trapezoid cuts down on the error of your area estimation. It is the average of the left and right rules.
Yes.
The trapezoidal rule is named for the shape of the geometric figure it uses to approximate the area under a curve. Specifically, it approximates the integral of a function by dividing the area into trapezoids rather than rectangles. By calculating the area of these trapezoids and summing them up, the rule provides an estimate of the total area under the curve. This method is particularly effective for functions that are relatively linear over small intervals.
i love wikipedia!According to wiki: In calculus, integration by substitution is a method for finding antiderivatives and integrals. Using the fundamental theorem of calculus often requires finding an antiderivative. For this and other reasons, integration by substitution is an important tool for mathematicians. It is the counterpart to the chain rule of differentiation.

explain how to find the rule in a numerical pattern
The trapezoidal rule is named for the shape of the geometric figure it uses to approximate the area under a curve.

Integration by parts is the integration of the product rule of differentiation. Used to transform a non-simple derivative integral into a simple antiderivative integral.
The accuracy of the trapezoidal rule is influenced by several factors, including: Function Behavior: The smoothness and continuity of the function being integrated; functions with more curves may lead to greater error. Interval Width: The size of the subintervals; smaller intervals generally yield more accurate results. Number of Subintervals: Increasing the number of trapezoids improves accuracy, as it better approximates the area under the curve. Endpoints: The choice of endpoints can affect the approximation, particularly if the function has significant variation near the edges. Higher Derivatives: The presence and magnitude of higher derivatives of the function can also impact the error; functions with large second derivatives can produce greater inaccuracies.

Write them in order, then 1.3499 is labelled 0, 1,88221 is 1, 2.4596 is 2. etc . It's just the convention for labelling successive ordinates.
