Abstract:
In this paper we use a technique given by Ibrahim, Dragomir and Mortici,
in order to prove and enunciate several inequalities starting from some classical
inequalities.
We present an improvement of Nesbitt’s inequality and also a reverse of
Nesbitt’s inequality. Other important results which appear in the paper are
some generalizations of well-known inequalities obtained by convergent power
series with positive coefficients.
