Trigonal bipyramidal crystal field, splitting orbitals

Fig. 20-8. The splitting pattern of the d orbitals in a trigonal-bipyramidal crystal field.

Develop a crystal field splitting diagram for the d orbitals of the metal in a trigonal bipyramidal complex [ML-] showing, qualitatively, how the energies of each of the d orbitals change. 

How will the d orbitals split in a trigonal bipyramidal environment Using a crystal field (pure point charge) model, determine what the relative energies of the orbitals will be.
