Abstract
The standard design principle for quadrature formulas is that they should be
exact for integrands of a given class, such as polynomials of a fixed degree.
We show how this principle fails to predict the actual behavior in four cases:
Newton-Cotes, Clenshaw-Curtis, Gauss-Legendre, and Gauss-Hermite quadrature.
Three further examples are mentioned more briefly.
