Abstract
In this paper, using the polynomial approximation and the continued fraction approximation, we present some sharp inequalities for the sequence \((1+1/n)^n\) and some applications to Carleman’s inequality. For demonstrating the superiority of our new inequalities over the classical one, some proofs and numerical computations are provided.
