    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
