tan(x)=0,4 (уравнение)

Найду корень уравнения: tan(x)=0,4

Вы ввели

tan(x) = 2/5

$$\tan{\left(x \right)} = \frac{2}{5}$$

Подробное решение

Дано уравнение
$$\tan{\left(x \right)} = \frac{2}{5}$$
- это простейшее тригонометрическое ур-ние
Это ур-ние преобразуется в
$$x = \pi n + \operatorname{atan}{\left(\frac{2}{5} \right)}$$
Или
$$x = \pi n + \operatorname{atan}{\left(\frac{2}{5} \right)}$$
, где n - любое целое число

Быстрый ответ

x1 = atan(2/5)

$$x_{1} = \operatorname{atan}{\left(\frac{2}{5} \right)}$$

Сумма и произведение корней

сумма

0 + atan(2/5)

$$0 + \operatorname{atan}{\left(\frac{2}{5} \right)}$$

=

atan(2/5)

$$\operatorname{atan}{\left(\frac{2}{5} \right)}$$

произведение

1*atan(2/5)

$$1 \operatorname{atan}{\left(\frac{2}{5} \right)}$$

=

atan(2/5)

$$\operatorname{atan}{\left(\frac{2}{5} \right)}$$
