Abstract In this paper, we study the completely monotonic property of two functions involving the function △(x) = 
and deduce the double inequality
, x > 0
which improve some recent results, where ψ(x) is the logarithmic derivative of the Gamma function. Also, we deduce the completely monotonic degree of a function involving ψ'(x). More >
