| Abstract: | By means of the parametric variational method, the differential equations of amplitude and phase of a two order non linear vibration system are established. The equations are then expanded with a special sphere polynomial as to obtain the approximate solutions, which are compared with others. |

| Keywords: | vibration sphere polynomial weighting orthometric system |
