  In this series of eight papers we present the applications of methods from
wavelet analysis to polynomial approximations for a number of accelerator
physics problems. In this part we consider a model for spin-orbital motion:
orbital dynamics and Thomas-BMT equations for classical spin vector. We
represent the solution of this dynamical system in framework of biorthogonal
wavelets via variational approach. We consider a different variational
approach, which is applied to each scale.
