Заполнение таблицы

Для перевода угловой меры из градусов в радианы и обратно используется основное соотношение: $180^\circ = \pi$ радиан.
Из этого соотношения следуют формулы для перевода:
1. Из градусов в радианы: $\alpha_{рад} = \alpha_{град} \cdot \frac{\pi}{180^\circ}$.
2. Из радиан в градусы: $\alpha_{град} = \alpha_{рад} \cdot \frac{180^\circ}{\pi}$.

Выполним вычисления для каждой пустой ячейки таблицы:
- Для угла $\frac{\pi}{6}$ радиан: $\alpha_{град} = \frac{\pi}{6} \cdot \frac{180^\circ}{\pi} = \frac{180^\circ}{6} = 30^\circ$.
- Для угла $45^\circ$: $\alpha_{рад} = 45^\circ \cdot \frac{\pi}{180^\circ} = \frac{45\pi}{180} = \frac{\pi}{4}$ радиан.
- Для угла $60^\circ$: $\alpha_{рад} = 60^\circ \cdot \frac{\pi}{180^\circ} = \frac{60\pi}{180} = \frac{\pi}{3}$ радиан.
- Для угла $90^\circ$: $\alpha_{рад} = 90^\circ \cdot \frac{\pi}{180^\circ} = \frac{90\pi}{180} = \frac{\pi}{2}$ радиан.
- Для угла $\frac{2\pi}{3}$ радиан: $\alpha_{град} = \frac{2\pi}{3} \cdot \frac{180^\circ}{\pi} = \frac{2 \cdot 180^\circ}{3} = 120^\circ$.
- Для угла $\frac{3\pi}{4}$ радиан: $\alpha_{град} = \frac{3\pi}{4} \cdot \frac{180^\circ}{\pi} = \frac{3 \cdot 180^\circ}{4} = 135^\circ$.
- Для угла $150^\circ$: $\alpha_{рад} = 150^\circ \cdot \frac{\pi}{180^\circ} = \frac{150\pi}{180} = \frac{5\pi}{6}$ радиан.
- Для угла $180^\circ$: $\alpha_{рад} = 180^\circ \cdot \frac{\pi}{180^\circ} = \pi$ радиан.

Заполненная таблица выглядит следующим образом (вписанные значения выделены жирным шрифтом):

$0^\circ$$30^\circ$$45^\circ$$60^\circ$$90^\circ$$120^\circ$$135^\circ$$150^\circ$$180^\circ$
$0$$\frac{\pi}{6}$$\frac{\pi}{4}$$\frac{\pi}{3}$$\frac{\pi}{2}$$\frac{2\pi}{3}$$\frac{3\pi}{4}$$\frac{5\pi}{6}$$\pi$

Ответ: Заполненная таблица представлена выше.

Отметка точек на координатной окружности

Изобразим координатную окружность с центром в начале координат $(0,0)$ и радиусом $R=3$ см. Отсчет углов производится от положительного направления оси абсцисс (оси Ox) против часовой стрелки. Каждому углу из таблицы соответствует точка на этой окружности.

xy033-3-3$0^\circ$$30^\circ$$45^\circ$$60^\circ$$90^\circ$$120^\circ$$135^\circ$$150^\circ$$180^\circ$

На рисунке выше красными точками отмечены положения на координатной окружности, соответствующие углам из таблицы. Для наглядности точки подписаны в градусах; их значения в радианах можно найти в таблице.

Ответ: Точки, соответствующие указанным углам, отмечены на координатной окружности выше.
