Abstract

A vertex-magic total labeling of graph , with the vertices  and the edges  is the bijection from  to the set of integers , and for each vertex  in  satisfying ,  is the vertex that adjacent with , then  named a magic constant in . The sum of the label of  and the labels of all edges  incident to the  is the same for all vertices of  and  named vertex-magic total graph. Vertex-magic total labeling of cartesian products of cycles, with the type , with  and  is odd are the labeling to the  and the concept used to label  is -vertex antimagic total labeling and to label  it is used vertex magic total labeling of cycles, with the cycle is odd.

Abstract

Gaus Quadrature Formula is better alternative than Newton Cotes Formula. The principal of Gaus Quadrature Formula determine unequal interval to minimize the error of approximation of integration. Formulation Gaus Quadrature on limited interval for numerical integration can use Hermite Interpolation Formula. Then, using the properties of Legendre polynomial which orthogonal on [-1,1] can determined nodes and weights. So, based on nodes and weight can be determined a Gaus – Legendre Quadratur Formula.
