“…However, owing to the problem of weak nonlinearities and small parameters, which are sometimes artificial, it makes it necessary to develop other analytical methods of solutions to overcome these limits (Filobello-Niño et al , 2013; Lim and Wu, 2002; Cheung et al , 1991). Consequently, the use of other analytical schemes such as differential transform method (DTM), homotopy analysis method (HAM), Adomian decomposition method (ADM), optimal homotopy asymptotic method (OHAM) and some other approximation methods has been developed (Lim and Wu, 2002; Cheung et al , 1991; Fakour et al , 2015; Hatami, 2017; Tang and Jing, 2017; Pourmehran et al , 2015, 2018; Ghasemi et al , 2014; Hatami and Ganji, 2014; Hatami et al , 2014a, b; Ganesan et al , 2014; Rahimi-Gorji et al , 2016; Biglarian et al , 2017; Mosayebidorcheh et al , 2017; Akinshilo, 2019, 2017; Sobamowo and Akinshilo (2017); Akinshilo and Ilegbusi, 2019; Akinshilo and Olofinkua, 2018; Dogonchi and Ganji, 2016a, b, c; Dogonchi et al , 2016, 2017; Ramsey and Tipton, 2017; Mehmood et al (2018); Pourmehran et al (2020)). Methods such as DTM, HAM and ADM, however, require the need to find an initial condition that will satisfy the boundary condition, for which theories have not been rigorously proven for all cases.…”
