\(50^\circ + k360^\circ ,\,\,k \in \mathbb{Z}.\)

\(50^\circ + k180^\circ ,\,\,k \in \mathbb{Z}.\)

\( - 50^\circ + k360^\circ ,\,\,k \in \mathbb{Z}.\)

\( - 50^\circ + k180^\circ ,\,\,k \in \mathbb{Z}.\)

\(\sin \left( {\alpha + \frac{\pi }{6}} \right) = \sin \alpha + \frac{1}{2}.\)

\(\sin \left( {\alpha + \frac{\pi }{6}} \right) = \frac{1}{2}\sin \alpha + \frac{{\sqrt 3 }}{2}\cos \alpha .\)

\(\sin \left( {\alpha + \frac{\pi }{6}} \right) = \frac{1}{2}\sin \alpha - \frac{{\sqrt 3 }}{2}\cos \alpha .\)

\(\sin \left( {\alpha + \frac{\pi }{6}} \right) = \frac{{\sqrt 3 }}{2}\sin \alpha + \frac{1}{2}\cos \alpha .\)

\( - 1.\)

\(\frac{1}{7}.\)

\( - \frac{1}{7}.\)

\(D = \mathbb{R}.\)

\(D = \mathbb{R}\backslash \left\{ 0 \right\}.\)

\(D = \mathbb{R}\backslash \left\{ {\frac{\pi }{2} + k\pi ,k \in \mathbb{Z}} \right\}.\)

\(D = \mathbb{R}\backslash \left\{ {k\pi ,k \in \mathbb{Z}} \right\}.\)

\[\left[ \begin{array}{l}x = \alpha + k2\pi \\x = \pi - \alpha + k2\pi \end{array} \right.\left( {k \in \mathbb{Z}} \right)\].

\[\left[ \begin{array}{l}x = \alpha + k\pi \\x = \pi - \alpha + k\pi \end{array} \right.\left( {k \in \mathbb{Z}} \right)\].

\[x = \pm \alpha + k2\pi \,\left( {k \in \mathbb{Z}} \right).\]

\[x = \alpha + k\pi \,\left( {k \in \mathbb{Z}} \right).\]

\(x = k\pi ,k \in \mathbb{Z}.\)

\(x = \frac{{k\pi }}{2},k \in \mathbb{Z}.\)

\(x = \frac{\pi }{2} + k\pi ,k \in \mathbb{Z}.\)

\(x = - \frac{\pi }{2} + k2\pi ,k \in \mathbb{Z}.\)
