Optimal error estimates for corrected trapezoidal rules

Erik Talvila, Matthew Wiersma

Corrected trapezoidal rules are proved for $\int_{a}^{b} f (x) d x$ under the assumption that $f " \in L^{p} ([a, b])$ for some $1 \leq p \leq \infty$ . Such quadrature rules involve the trapezoi…

Simple derivation of basic quadrature formulas

Erik Talvila, Matthew Wiersma

Simple proofs of the midpoint, trapezoidal and Simpson's rules are proved for numerical integration on a compact interval. The integrand is assumed to be twice continuously differe…

Quadrature rules with (not too many) derivatives

Matthew Wiersma

Quadrature formulas for $\int_{a}^{b} f (x) d x$ where derivative terms need only be evaluated at $a$ and $b$ in the composite rule are identified. Error bounds are given when $f:[a,b]\t…
