✦ Synopsis
This communication aims to report the corrections to HAM results presented in a paper by Ghotbi [1]. The graphical results presented by Ghotbi are observed to be divergent as a consequence of the bad selection of the values of auxiliary parameter h. Further, the results presented by Ghotbi do not agree with the exact solution for g P 2:5. We present highly accurate and convergent HAM solutions which is in good agreement with the exact solution for the entire spatial domain 0 6 g < 1. A comparison between the present HAM solution and the exact solution has been reported and both the solutions are found to be in good agreement.
