ctg(x)=1 (уравнение)

Найду корень уравнения: ctg(x)=1

Вы ввели

cot(x) = 1

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

Подробное решение

Дано уравнение
$$\cot{\left(x \right)} = 1$$
преобразуем
$$\cot{\left(x \right)} - 1 = 0$$
$$\cot{\left(x \right)} - 1 = 0$$
Сделаем замену
$$w = \cot{\left(x \right)}$$
Переносим свободные слагаемые (без w)
из левой части в правую, получим:
$$w = 1$$
Получим ответ: w = 1
делаем обратную замену
$$\cot{\left(x \right)} = w$$
подставляем w:
