tgx=1/2 (уравнение)

Найду корень уравнения: tgx=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

Сумма и произведение корней

сумма

0 + atan(1/2)

$$0 + \operatorname{atan}{\left(\frac{1}{2} \right)}$$

=

atan(1/2)

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

произведение

1*atan(1/2)

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

=

atan(1/2)

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

Быстрый ответ

x1 = atan(1/2)

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