cos(x-pi)=1 (уравнение)

Найду корень уравнения: cos(x-pi)=1

Вы ввели

cos(x - pi) = 1

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

Подробное решение

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

Разделим обе части ур-ния на -1

Ур-ние превратится в
$$\cos{\left(x \right)} = -1$$
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

Быстрый ответ

x1 = pi

$$x_{1} = \pi$$
