The associated chord separates the interior into two segments. Let A1 be the area of the larger and A2 the area of the smaller. The term "ratio of segment areas" means A1/A2. See A336073 for a guide to related sequences. %F A336079 ratio = (2*Pi - s + sin(s))/(s - sin(s)), where s = 1. %e A336079 ratio = 38.63429218030340056508641778759493689126124881320... %t A336079 s = 1; r = N[(2 Pi - s + Sin[s])/(s - Sin[s]), 200] %t A336079 RealDigits[r][[1]] %Y A336079 Cf.
