A Taylor series method is derived to construct an analytical solution for the quantum anharmonic oscillator. The expression presented is found to yield in a rather natural way the corresponding special result obtained by using perturbation theoretic techniques. Attempts are made to give a possible physical interpretation for the various terms originating from nonlinear effects. Numerical results are presented to develop a feeling for their relative importance.
