How many number of sub-intervals required to use Trapezoidal rule in numerical integration?
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.
Why is Trapezoidal rule better than Riemann left right rule?
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.
Use Trapezoidal rule to evaluate the approximate values of definite integrals?
Yes.
How do you calculate area under the hydrograph curve?
To calculate the area under a hydrograph curve, you can use numerical integration techniques, such as the trapezoidal rule. First, divide the hydrograph into segments, typically between time intervals where flow rates are measured. Then, for each segment, calculate the area as the average of the flow rates at the two endpoints multiplied by the time interval. Finally, sum the areas of all segments to obtain the total area under the curve, which represents the total volume of water passing a point over the specified time period.
Why trapezoidal rule is so called?
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.

This method is particularly effective for functions that are relatively linear over small intervals.
What are five factors that affect the accuracy of the trapezoidal rule?
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.
How does one do integration by parts?
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.

Why are the numbers 1.3499 2.4596 4.4817 classed as even numbers And 1.8221 3.3201 are classified as odd numbers in numerical integration simpsons rule?
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.
