%0 Journal Article %T How to obtain Lie point symmetries of PDEs %A Kadhim, Sajid Mohammad %A Mohammad, Mayada Gassab %A Jassim, Hassan Kamil %J Journal of Mathematics and Computer Science %D 2021 %V 22 %N 4 %@ ISSN 2008-949X %F Kadhim2021 %X In this research, we have studied how to obtain Lie point symmetries of a partial differential equation (PDEs) of second order. We have also studied some PDEs' applications as one-dimensional and two-dimensional heat equations. We have used Manale's formula for solving second-order ordinary differential equations to determine new symmetries. Burgers equation has been studied, and Lie point symmetries have been obtained for these equations. %9 journal article %R 10.22436/jmcs.022.04.01 %U http://dx.doi.org/10.22436/jmcs.022.04.01 %P 306--324
