Trapezoidal rule and simpson.

Here the trapezoidal rule approximates the function by a suitable chosen (not necessarily horizontal) line segment. The function values at two points in the interval are used in the approximation. While Simpson's rule uses a suitably chosen parabolic shape (see Section 4.6 of the text) and uses the function values at three points.

Introduction. Simpson’s Rule is a numerical method used in calculus to estimate definite integrals. While it’s a powerful technique, it’s essential to assess the accuracy of the results it provides.Here the trapezoidal rule approximates the function by a suitable chosen (not necessarily horizontal) line segment. The function values at two points in the interval are used in the approximation. While Simpson's rule uses a suitably chosen parabolic shape (see Section 4.6 of the text) and uses the function values at three points.

Like the Trapezoidal Rule, Simpson's Rule is another numerical integration technique used to approximate an integral that may be too difficult to compute directly. Unlike the Trapezoidal Rule, Simpson's Rule uses quadratic polynomial approximation, making it a more accurate integral estimation technique.

The trapezoidal rule and Simpson’s rule are two of the most popular numerical integration methods. However, few people know how to choose between them. This is because these methods have a lot in common: they both use polynomials as their basic functions, and they both require an even number of function evaluations.

The trapezoidal rule is one method we can use to approximate the area under a function over a given interval.
