sint=1/2 (уравнение)

Найду корень уравнения: sint=1/2

Вы ввели

sin(t) = 1/2

$$\sin{\left(t \right)} = \frac{1}{2}$$

Подробное решение

Дано уравнение
$$\sin{\left(t \right)} = \frac{1}{2}$$
- это простейшее тригонометрическое ур-ние
Это ур-ние преобразуется в
$$t = 2 \pi n + \operatorname{asin}{\left(\frac{1}{2} \right)}$$
$$t = 2 \pi n - \operatorname{asin}{\left(\frac{1}{2} \right)} + \pi$$
Или
$$t = 2 \pi n + \frac{\pi}{6}$$
$$t = 2 \pi n + \frac{5 \pi}{6}$$
, где n - любое целое число
