Variation of paramets method for squeezed flow of a Casson fluid

The implementation of the variation of parameters method has been demonstrated for the flow of a Casson fluid through squeezed parallel plates. Governing PDE has been reduced, with the help of similarity transform, to relatively simpler ODE. The consequent non-linear equation is complicated enough to have an exact solution. We have solved that with the help of variation of parameters method. The results are displayed with the help of graphs and are decorated with suitable physical explanation.
