%0 Journal Article %T Lie group and RK4 for solving nonlinear first order ODEs %A Sami H. Altoum %J - %D 2016 %R 10.14419/ijamr.v5i2.6033 %X This paper deals with a numerical comparison between Lie group method and RK4 for solving an nonlinear ordinary differential equation. The Lie group method will be introduced as a analytical method and then compared to RK4 as a numerical method. Some examples will be considered and the global error we be computed numerically. %U https://www.sciencepubco.com/index.php/ijamr/article/view/6033
