Abstract:In this paper, based on continued fractions, some faster asymptotic formulas of gamma, psi and psi's derivative functions are given. Then, we provide some relevant inequalities. Finally, in order to demonstrate that our new asymptotic formulas have superiority, some numerical computations are also given.
