A convergence criterion for tangent hyperbolic fluid along a stretching wall subjected to inclined electromagnetic field

The homotopy-based approach is a useful tool for solving nonlinear partial differential equations (PDEs) in physics and engineering. Our aim here is to optimize this approach by generating a convergence criterion for tangent hyperbolic fluid along a stretching wall with magnetic force. To this end, the governing partial differential equations (PDEs) get transformed to the dimensionless form via similarity variables. A comparison of the homotopy-based approach for the skin friction coefficient with different solution methodologies shows that the 9th-order approximate solution together with ħ = - 0.523 will certainly achieve a very minor error for the present system.
