Re: [math-fun] Can someone identify this number? : 0.33650841691839529162

Hello, I just tested that number (0.33650841691839529162) well with 20 digits, not much came out. I have this approximation ; -5 Pi Csch[Sqrt[5] Pi] + 3 Sec[Sqrt[5] Pi] - Sin[Sqrt[5] Pi] ------------------------------------------------------------ 10 which is good to 11 digits. but 11 digits this is half of an answer. simon plouffe
