The aim of the present paper is to obtain derivatives of the Jacobi polynomials with two variables on the triangle with respect to their parameters by using the parameter derivatives of the classical Jacobi polynomials P-n((alpha,beta))(x). Furthermore, we give orthogonality properties of the parametric derivatives on the triangle. (C) 2014 Elsevier Inc. All rights reserved.
