| Abstract | ||
| This paper introduces four approximate formulas for calculating r (x), x ε R+. They produce approximate values which are "very close " to the tabulated ones. One of the formulas gives correct results up to at least five decimal places. These formulas were compared according to what we call "The Uniformly Best Criterion". | ||
