Extension of Dasgupta’s Technique for Higher Degree Approximation

In the present paper, rational wedge functions for degree two approximation have been computed over a pentagonal discretization of domain, by using an analytic approach which is extension Dasgupta’s linear approximation. This technique allows to avoid computation exterior intersection points elements, was key component initiated Wachspress. The necessary condition existence denominator function established Wachspress whereas our assertion, induced Dasgupta, assures sufficiency existence. Considering adjoint (denominator) obtained invariance established. other words, method proposed Dasgupta construction ofWachspress coordinates extended obtain quadratic assertions supported considering some illustrative examples.
