Найду корень уравнения: Cosx=1

Вы ввели

cos(x) = 1

$$\cos{\left(x \right)} = 1$$

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
$$x = \pi n$$
$$x = \pi n - \pi$$
, где n - любое целое число
