Abstract

UJEVIC, NENAD and MIJIC, LUCIJA. An optimal 3-point quadrature formula of closed type and error bounds. Rev.colomb.mat. [online]. 2008, vol.42, n.2, pp.209-220. ISSN 0034-7426.

An optimal 3-point quadrature formula of closed type is derived. The obtained optimal quadrature formula has better estimations of error than the well-known Simpson's formula. A few error inequalities for this formula are established.

Keywords : Optimal quadrature formula; error inequalities; Ostrowski-like inequalities.
