Soluções gerais para

sin (\frac{x π}{11}) = sin (\frac{π}{11})

sin (x) = a \Rightarrow x = arcsin (a) + 2 πn, x = π - arcsin (a) + 2 πn

\frac{x π}{11} = arcsin (sin (\frac{π}{11})) + 2 πn, \frac{x π}{11} = π - arcsin (sin (\frac{π}{11})) + 2 πn

\frac{x π}{11} = arcsin (sin (\frac{π}{11})) + 2 πn, \frac{x π}{11} = π - arcsin (sin (\frac{π}{11})) + 2 πn
