Key words: reduced differential transform method, symmetric regularized long wave, coupled problem, and mixed partial derivatives.
The most of the problems dealt in the context of RDTM did not deal with the coupled problem when there are mixed partial derivatives.
And the reduced differential transformation of mixed partial derivatives term of SRLWE (1) was
Since, partial differential equations in the coupled problem under consideration had complicated mixed partial derivatives (Handibag and Karande, 2012).
It was worth mentioning that most of the problems dealt in the context of the reduced differential transform method did not deal with the coupled problem when there were mixed partial derivatives.
This study was important for the coupled problem when nonlinearity and mixed partial derivatives occurred in the system of equations.
