Hello, me too (and probably many other people as well), with cos and 1/x you get the fixed point of cos(x) = x which is 0.7390851332151... but also : with x^2 fives times and log, I found that log(163) = 163/32 very nearly. and then by chance once in 1987 on my hp calculator that exp(Pi) - Pi is very near 20, 19.9990999... I am still wondering why. that log(13981) = 9.5454545439878... which is 105/11 almost. that the sqrt(62) = 7.874007874... sqrt(51)/14 = 0.51010203061020... but for that one , we can find that we have the central binomial coefficients in zig-zag. I am sure, there are others out there. Best regards, Simon Plouffe
