tg(x) = -1/2 (уравнение)

Найду корень уравнения: tg(x) = -1/2

Вы ввели

tan(x) = -1/2

$$\tan{\left(x \right)} = - \frac{1}{2}$$

Подробное решение

Дано уравнение
$$\tan{\left(x \right)} = - \frac{1}{2}$$
- это простейшее тригонометрическое ур-ние
Это ур-ние преобразуется в
$$x = \pi n + \operatorname{atan}{\left(- \frac{1}{2} \right)}$$
Или
$$x = \pi n - \operatorname{atan}{\left(\frac{1}{2} \right)}$$
, где n - любое целое число

Быстрый ответ

x1 = -atan(1/2)

$$x_{1} = - \operatorname{atan}{\left(\frac{1}{2} \right)}$$
