In our present paper, we have obtained approximate solutions of non-linear quadratic Riccati differential equations using the Galerkin method. We considered Fibonacci polynomials and then Lucas polynomials as basis functions i.e., we presented two numerical methods: Fibonacci Galerkin method and Lucas Galerkin method. We have given some applications of this method by solving some differential equations. Then compare the approximate solution with the exact solution and approximate solutions with other methods. From this comparison and error analysis we can say that our method gives better results.
