cot(x)=1/3 (уравнение)

Найду корень уравнения: cot(x)=1/3

Вы ввели

cot(x) = 1/3

$$\cot{\left(x \right)} = \frac{1}{3}$$

Подробное решение

Дано уравнение
$$\cot{\left(x \right)} = \frac{1}{3}$$
преобразуем
$$\cot{\left(x \right)} - \frac{1}{3} = 0$$
$$\cot{\left(x \right)} - \frac{1}{3} = 0$$
Сделаем замену
$$w = \cot{\left(x \right)}$$
Переносим свободные слагаемые (без w)
из левой части в правую, получим:
$$w = \frac{1}{3}$$
Получим ответ: w = 1/3
делаем обратную замену
$$\cot{\left(x \right)} = w$$
подставляем w:

Быстрый ответ

x1 = acot(1/3)

$$x_{1} = \operatorname{acot}{\left(\frac{1}{3} \right)}$$

Сумма и произведение корней

сумма

0 + acot(1/3)

$$0 + \operatorname{acot}{\left(\frac{1}{3} \right)}$$

=

acot(1/3)

$$\operatorname{acot}{\left(\frac{1}{3} \right)}$$

произведение

1*acot(1/3)

$$1 \operatorname{acot}{\left(\frac{1}{3} \right)}$$

=

acot(1/3)

$$\operatorname{acot}{\left(\frac{1}{3} \right)}$$
