Re: [math-fun] about a certain François Mendzina Essomba and surprising pi formulas

here is a copy of the images on facebook : http://plouffe.fr/FME/

Simon's link contains 3 jpg image links. Essomba's offering actually has 4 pages. Simon's FMessomba2.jpg and FMessomba3.jpg correspond to Essomba's pages 2 and 3 but FMessomba1.jpg corresponds to page 4. Essomba's page 1 sets up (in French) his "challenge". I've created a pdf with all 4 pages here: http://chesswanks.com/txt/FMEpi.pdf
