High degree quadrature rules with pseudorandom rational nodes

Mário M. Graça

After introducing the definitions of positive, negative and companion rules, from a given pair of companion rules we construct a new rule with higher degree of precision The scheme…

Four beautiful quadrature rules

Mário M. Graça

A framework is presented to compute approximations of an integral $I (f) = \int_{a}^{b} f (x) d x$ from a pair of companion rules and its associate rule. We show that an assoc…
