Y1 - 2014 PY - 2014 VL - 01 IS - 2 SP - 31 EP - 37 KW - Euler function KW - Coprime integers KW - Asymptotic behaviour of the sequence DO - N2 - The asymptotic behaviour of the sequence with general term $P_n=(\varphi(1)+\varphi(2)+\cdots+\varphi(n))/(1+2+\cdots+n)$, is studied which appears in the studying of coprime integers, and an explicit bound for the difference $P_n-6/\pi^2$ is found.
