    We use a direct variational method in order to investigate the dependence on parameter for the solution of the following Du_ng type equation with Dirichlet boundary conditions x(t) + r(t)x_ (t) Fx(t; x(t)) f(t) = 0 x(0) = x(1) = 0 and we observe that some outline of variational approach, in order to use this method. Key Words and phrases:Dirichlet boundary problem,Du_ng equation and Lower semicontinuity
