| Sumario: | We prove the following very accurate approximation formula for the factorial function: <img src="http:/fbpe/img/proy/v32n2/art6.1.jpg" name="_x0000_i1029" width=383 height=46 id="_x0000_i1029"> This gives better results than the following approximation formula <img src="http:/fbpe/img/proy/v32n2/art6.2.jpg" name="_x0000_i1028" width=455 height=49 id="_x0000_i1028"> which is established by the author [5] and C. Mortici [16] independently, and gives similar results with <img src="http:/fbpe/img/proy/v32n2/art6.3.jpg" name="_x0000_i1027" width=369 height=48 id="_x0000_i1027"> which is established by C. Mortici in his very new paper [8]. |
