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

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

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

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

\[S = \left\{ {k2\pi ;\frac{\pi }{3} + k2\pi |k \in \mathbb{Z}} \right\}\].

\[S = \left\{ {k2\pi ;\frac{\pi }{3} + k\frac{{2\pi }}{3}|k \in \mathbb{Z}} \right\}\].

\[S = \left\{ {k2\pi ; - \frac{\pi }{3} + k2\pi |k \in \mathbb{Z}} \right\}\].

\[{u_3} = - 6\].

\[{u_2} = 4\].

\[{u_4} = - 8\].

\[{u_1} = - 2\].

\[{u_{2n - 1}} = {3^{2\left( {n - 1} \right)}}\].

\[{u_{2n - 1}} = {3^{2n}} - 1\].

\[{u_{2n - 1}} = {3^n} \cdot {3^{n - 1}}\].

\[{u_{2n - 1}} = {3^2} \cdot {3^n} - 1\].
