tan(2*x)=1 (уравнение)

Найду корень уравнения: tan(2*x)=1

Вы ввели

tan(2*x) = 1

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

Подробное решение

Дано уравнение
$$\tan{\left(2 x \right)} = 1$$
- это простейшее тригонометрическое ур-ние
Это ур-ние преобразуется в
$$2 x = \pi n + \operatorname{atan}{\left(1 \right)}$$
Или
$$2 x = \pi n + \frac{\pi}{4}$$
, где n - любое целое число
Разделим обе части полученного ур-ния на
$$2$$
получим ответ:
$$x_{1} = \frac{\pi n}{2} + \frac{\pi}{8}$$

Быстрый ответ

x1 = --
     8 

$$x_{1} = \frac{\pi}{8}$$
