Higazy was born in Teta Village, Menouf, Menoufia, Egypt in 1976. Navigate Left Previous article in issue.Results of the present paper show that the Sawi transformation provides us the exact solution of SODEs without large computational work. Results of this problem are visualized using tables and graphs. Authors have obtained the solution of this problem by developing its mathematical model in terms of SODEs and then applying Sawi transformation on it. After it, authors have taken a problem of physical chemistry for determining the concentration of chemical reactants (substances) of chemical reaction in series. Authors have considered four numerical problems and determined their solutions step by step for explaining the complete method. In the present paper, authors used Sawi transformation for finding the solution of SODEs with application to determine the concentration of chemical reactants of chemical reaction in series. The problem of motion of coupled harmonic oscillators can be modeled in the terms of system of ordinary differential equations (SODEs). ![]()
