Our aim is to use second-order ordinary differential equations derived from the first-order ordinary differential equations in order to resolve this important deficiency for the first-order ordinary differential equations. Before we mention about finding the Lie symmetries of the ordinary differential equations briefly. Later on we present some of the examples related with the subject. © 2013 AIP Publishing LLC.On the lie symmetries of first-order ordinary differential equationsConference paper10.1063/1.4826064
