\[1)\sin x = 0,65\]
\[x = ( - 1)^{n} \bullet \arcsin{0,65} + \pi n\]
\[x \approx ( - 1)^{n} \bullet 0,7075 + \pi n\ .\]
\[2)\sin x = - 0,31\]
\[x = ( - 1)^{n} \bullet \left( - \arcsin{0,31} \right) = \pi n\]
\[x = ( - 1)^{n + 1} \bullet \arcsin{0,31} + \pi n\]
\[x \approx ( - 1)^{n + 1} \bullet 0,3151 + \pi n.\]
