sin(-x)=-1 (уравнение)

Найду корень уравнения: sin(-x)=-1

Вы ввели

sin(-x) = -1

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

Подробное решение

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

Разделим обе части ур-ния на -1

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