 OFFSET 1,3 COMMENTS Also the least positive x such that sin(exp(x))==0. See 1991 Mathematica Conference, Elementary Tutorial Notes, page 25. Also real part of log(log(-1)). - Stanislav Sykora, May 11 2015 LINKS G. C. Greubel, Table of n, a(n) for n = 1..5000 FORMULA Equals log(log(-1)) - (Pi/2)*I. - Stanislav Sykora, May 11 2015 Equals 1 + Sum_{n>=1} Zeta(2*n)/(n*(2*n+1)*2^(2*n)), where Zeta is the Riemann Zeta function. - Vaclav Kotesovec, Mar 04 2016 EXAMPLE 1.1447298858494001741...
