MODIFIKASI METODE ITERASI VARIASIONAL LAPLACE UNTUK MENYELESAIKAN PERSAMAAN DIFERENSIAL PARSIAL PARABOLIK ORDE EMPAT

Abstract

This article discusses a modification of Laplace variational iteration method to solve a fourth-order parabolic partial differential equations with variable coefficient. Modification is made by coupling of three methods. The application process begins by converting the equation to be solved by forming a correction functions, Laplace transform, and transform correction function by pertubation homotopy method. This correction function obtain an approximation form as a series solution
