WebSep 3, 2024 · 1. I think there's no elementary formula for this. Denote arc and chord as a, b, then r θ = a, 2 r sin ( θ / 2) = b. Divide the first equation by the second, we get. θ 2 sin ( θ / 2) = a b θ = 2 a b sin ( θ / 2). Subsitute θ / 2 with u, we get. u = a b sin u. which is an equation you can't give simple solution to.
