Greubel, Table of n, a(n) for n = 1..5000 Eric Weisstein's World of Mathematics, Hyperbolic Sine Eric Weisstein's World of Mathematics, Hyperbolic Functions Eric Weisstein's World of Mathematics, Factorial Sums FORMULA sinh(1) = (e - e^(-1))/2. Equals sum_{n>=0} 1/A009445(n). See Gradsteyn-Ryzhik (0.245.6.) - R. J. Mathar, Oct 27 2012 Continued fraction representation: sinh(1) = 1 + 1/(6 - 6/(21 - 20/(43 - 42/(73 - ... - (2*n - 1)*(2*n - 2)/((2*n*(2*n + 1) + 1) - ... ))))). See A051397 for proof. Cf.
