In this paper, we present the best possible parameters [Formula: see text] and [Formula: see text] such that the double inequality [Formula: see text] holds for all [Formula: see text] and [Formula: see text] with [Formula: see text], and we provide new bounds for the complete elliptic integral [Formula: see text] [Formula: see text] of the second kind, where [Formula: see text], [Formula: see text] and [Formula: see text] are the Toader, arithmetic, and quadratic means of and , respectively.
在本文中,我们给出了最佳可能的参数[公式:见正文]和[公式:见正文],使得双重不等式[公式:见正文]对所有满足[公式:见正文]的[公式:见正文]和[公式:见正文]都成立,并且我们为第二类完全椭圆积分[公式:见正文][公式:见正文]提供了新的界,其中[公式:见正文]、[公式:见正文]和[公式:见正文]分别是[公式:见正文]和[公式:见正文]的托阿德均值、算术均值和二次均值。
