sin(-x)=-1/2 (уравнение)

Найду корень уравнения: sin(-x)=-1/2

Вы ввели

sin(-x) = -1/2

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

Подробное решение

Дано уравнение
$$\sin{\left(- x \right)} = - \frac{1}{2}$$
- это простейшее тригонометрическое ур-ние

Разделим обе части ур-ния на -1

Ур-ние превратится в
$$\sin{\left(x \right)} = \frac{1}{2}$$
Это ур-ние преобразуется в
$$x = 2 \pi n + \operatorname{asin}{\left(\frac{1}{2} \right)}$$
$$x = 2 \pi n - \operatorname{asin}{\left(\frac{1}{2} \right)} + \pi$$
Или
$$x = 2 \pi n + \frac{\pi}{6}$$
$$x = 2 \pi n + \frac{5 \pi}{6}$$
, где n - любое целое число
