Подробное решение

Дано уравнение
$$\cos{\left(x \right)} = -1$$
- это простейшее тригонометрическое ур-ние
Это ур-ние преобразуется в
$$x = \pi n + \operatorname{acos}{\left(-1 \right)}$$
$$x = \pi n - \pi + \operatorname{acos}{\left(-1 \right)}$$
Или
$$x = \pi n + \pi$$
$$x = \pi n$$
, где n - любое целое число
