论文摘要
由J.Sándor[19]的工作激发,在本文中,我们建立了一种新的Wilker类型和Huygens型不平等,涉及三角和双曲线功能。此外,就双曲线功能而言,给出了SIN(x)/x和tan(x)/x的上限和下限。
Motivated by the work of J. Sándor [19], in this paper we establish a new Wilker type and Huygens type inequalities involving the trigonometric and hyperbolic functions. Moreover, in terms of hyperbolic functions, the upper and lower bounds of sin(x)/x and tan(x)/x are given.
