A Proposed Numerical Integration Method Using Polynomial Interpolation

Kwasi A. Darkwah, Ezekiel N. N. Nortey & Charles Anani Lotsi · Journal of Advances in Mathematics and Computer Science · 2016

The main aim of this paper is to propose a numerical integration method using polynomial interpolation that provides improved estimates as compared to the Newton-Cotes methods of integration. The method is an extension of trapezoidal rule where the Lagrange interpolation is emplo...
