Mixed partial derivative are calculated by the same rules, which are applied to interpolation polynomials along axes [xi] and [eta].
The most of the problems dealt in the context of RDTM did not deal with the coupled problem when there are mixed partial derivatives. The current study deals with mainly such type of implications of partial differential equations.
Since, partial differential equations in the coupled problem under consideration had complicated mixed partial derivatives (Handibag and Karande, 2012).
These derivatives cover all the partial derivatives of [[alpha].sup.r] with respect to composition, [tau], [delta], and mixed partial derivatives thereof.
