Sažetak
The weighted version of the corrected two-point quadrature formula is derived. In the corrected two-point formula the integral is approximated both with the values of the integrand in nodes $x$ and $a+b-x$, and the values of its first derivative in the end-points of the interval $[a, b]$. Those formulae have a degree of exactness higher than the ordinary formulae. Estimates of error bounds under various regularity conditions for such formulae are established. As special cases, the corrected two-point formulae of Gauss type are obtained. Also, the corrected version of weighted trapezoid, weighted midpoint, weighted two-point Maclaurin and weighted two-point Newton-Cotes formulae are considered.
