cos(-t)=-1 (уравнение)

Найду корень уравнения: cos(-t)=-1

Вы ввели

cos(-t) = -1

$$\cos{\left(- t \right)} = -1$$

Подробное решение

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

Быстрый ответ

t1 = pi

$$t_{1} = \pi$$
