Abstract

A boundary type quadrature formula (BTQF) is an approximate integration formula with all its of evaluation points lying on the Boundary of the integration domain. This type formulas are particularly useful for the cases when the values of the integrand functions and their derivatives inside the domain are not given or are not easily determined. In this paper, we will establish the BTQFs over sonic axially symmetric regions. We will discuss time following three questions in the construction of BTQFs: (i) What is the highest possible degree of algebraic precision of the BTQF if it exists? (ii) What is the fewest number of time evaluation points needed to construct a BTQF with the highest possible degree of algebraic precision? (in) How to construct the BTQF with the fewest evaluation points and the highest possible degree of algebraic precision?
