Помоги найти значения sin 135°, cos 135°, tg 135°, ctg 135°, sin 150°, cos 150°, tg 150°, ctg 150°

1. Найдем $\sin 135^\circ$, $\cos 135^\circ$, $\tan 135^\circ$ и $\cot 135^\circ$: $\sin 135^\circ = \sin (180^\circ - 45^\circ) = \sin 45^\circ = \frac{\sqrt{2}}{2}$ $\cos 135^\circ = \cos (180^\circ - 45^\circ) = -\cos 45^\circ = -\frac{\sqrt{2}}{2}$ $\tan 135^\circ = \frac{\sin 135^\circ}{\cos 135^\circ} = \frac{\frac{\sqrt{2}}{2}}{-\frac{\sqrt{2}}{2}} = -1$ $\cot 135^\circ = \frac{1}{\tan 135^\circ} = -1$ 2. Найдем $\sin 150^\circ$, $\cos 150^\circ$, $\tan 150^\circ$ и $\cot 150^\circ$: $\sin 150^\circ = \sin (180^\circ - 30^\circ) = \sin 30^\circ = \frac{1}{2}$ $\cos 150^\circ = \cos (180^\circ - 30^\circ) = -\cos 30^\circ = -\frac{\sqrt{3}}{2}$ $\tan 150^\circ = \frac{\sin 150^\circ}{\cos 150^\circ} = \frac{\frac{1}{2}}{-\frac{\sqrt{3}}{2}} = -\frac{1}{\sqrt{3}} = -\frac{\sqrt{3}}{3}$ $\cot 150^\circ = \frac{1}{\tan 150^\circ} = -\sqrt{3}$ *Перевод:* 1.
