Application of variational iteration method to find the solution of coupled system of first order differential equations

Abstract

Present work is devoted to the application of variational iteration method to obtain the solutions of coupled system of first order differential equations. Numerical examples are taken to test the efficiency of this method. We have shown that the successive approximations of each problem are converging to their exact solution. Further we have shown graphically the third, fourth, fifth and sixth approximation values and exact values.
