Key Concepts

Simpson's Rule

Simpson's Rule is a numerical integration technique that improves on the Trapezoidal Rule by using quadratic polynomials to approximate the function over pairs of subintervals. This method often yields a higher degree of accuracy by accounting for the curvature of the function more effectively.

Simpson's Rule Error Bound

The error bound for Simpson's Rule estimates the maximum possible error in the approximation and is dependent on the fourth derivative of the function over the interval. By analyzing this error bound, one can determine the number of subintervals required to ensure that the approximation error meets a given tolerance.

Trapezoidal Rule Error Bound

The error bound for the Trapezoidal Rule provides an estimate of the maximum error produced when using the method. It is typically expressed in terms of the width of the subintervals and the maximum absolute value of the second derivative of the function over the integration interval. This error bound is used to determine the number of subintervals needed to achieve a desired accuracy.

Numerical Integration

Numerical integration is the process of approximating the value of a definite integral, especially when an antiderivative is difficult or impossible to find analytically. It involves techniques that sum values of the integrand at specific points, multiplied by a width, to approximate the area under the curve.

Trapezoidal Rule

The Trapezoidal Rule is a numerical integration method that approximates the area under a curve by dividing the integration interval into subintervals and approximating the region under the curve in each subinterval by a trapezoid. Its simplicity comes with an associated error that depends on the second derivative of the function.
