Good morning, May I introduce myself.My name is Saowaluk Khamserr. I am studying at the faulty of science, Mahasarakham university in Thailand. I am fourth-year. Now I am interested in the Modified Laplace Decomposition Method for Lane-Emden Type Differential Equations paper but I don't understand a part of your paper. This part is integrating both sides of Eq. (12) from 0 to s respect with s. It has problem, when I have integrated this equation as I get Eq. (13) and then I used Eq.(13) for solving the example in your paper. For example,I encounter when I have taked the lower bound of integrating,and then the denominator is zero same as I can not find it's answer the same your paper. Thus, I would like to know source of value of integrating from 0 to s respect with s thoroughly. Any advice, could you please suggest.
