  We present several exact solutions to the coupled nonlinear Gross-Pitaevskii
equations which describe the motion of the one-dimensional spin-2 Bose-Einstein
condensates. The nonlinear density-density interactions are decoupled by making
use of the properties of Jacobian elliptical functions. The distinct time
factors in each hyperfine state implies a "Lamor" procession in these
solutions. Furthermore, exact time-evolving solutions to the time-dependent
Gross-Pitaevskii equations are constructed through the spin-rotational symmetry
of the Hamiltonian. The spin-polarizations and density distributions in the
spin-space are analyzed.
