Constant that improve (double) factorial
Constant that improve (double) factorial
The purpose of this paper is to discuss and refine some recent results of Bauer [Remark on Stirling’s formula and on approximations for the double factorial, Mathematical Intelligencer, 29, (2007),10-14] and Brede [On the convergence of the sequence defining Euler’s number Mathematical Intelligencer, 27, (2005), 6-7].
