New three-stages symmetric six-step finite difference method with vanished phase-lag and its derivatives up to sixth derivative for second order initial and/or boundary value problems with periodical and/or oscillating solutions

In this paper, for the first time in the literature, we develop a symmetric three-stages six-step method with the following characteristics; the method is a symmetric hybrid (multistages) six-step method, is of three-stages, is of twelfth algebraic order, has vanished the phase-lag and has vanished...
