      abstract = {We further develop a simple and compact technique for  calculating the three flavor neutrino oscillation  probabilities in uniform matter density. By performing  additional rotations instead of implementing a perturbative  expansion we significantly decrease the scale of the  perturbing Hamiltonian and therefore improve the accuracy  of zeroth order. We explore the relationship between  implementing additional rotations and that of performing a  perturbative expansion. Based on our analysis, independent  of the size of the matter potential, we find that the first  order perturbation expansion can be replaced by two  additional rotations and a second order perturbative  expansion can be replaced by one more rotation. Numerical  tests have been applied and all the exceptional features of  our analysis have been verified.},
