Some new estimates of precision of Cusa-Huygens and Huygens approximations

Branko Malesevic, Marija Nenezic, Ling Zhu +2

In this paper we present some new upper bounds of the Cusa-Huygens and the Huygens approximations. Bounds are obtained in the forms of some polynomial and some rational functions.

Some estimates of precision of the Huygens approximation

Branko Malesevic, Marija Nenezic, Ling Zhu +1

In this paper are given some estimates of precision of the Huygens approximation $x \approx \frac{2}{3} sin x + \frac{1}{3} tan x,$ for right neighbourhood of zero, by determinin…
