Many applications of various self-adjoint differential equations, whose solutions are complex, are produced Arfken, 1985; Gandarias, 2011; and Delkhosh, 2011 . In this work we propose a method for the solving some self-adjoint equations with variable change in problem, and then we obtain a analytical solutions. Because this solution, an exact analytical solution can be provided to us, we benefi...
